Subject: 1.1) What is an Atari 8-bit computer?

Based in Silicon Valley in the U.S.A., the company known as Atari produced
a line of home computers from 1979 to 1992 often referred to collectively as
the "Atari 8-bits," the "8-bit Ataris," the "400/800/XL/XE series," etc.

The computers included the 400, 800, 1200XL, 600XL, 800XL, 65XE, 130XE,=
 800XE,
and the XE Game System.

These machines competed in the marketplace most directly with the likes of=
 the
Commodore 64 series, the Apple II series, the Texas Instruments TI99/4A, and
the Radio Shack Color Computer, among others.  Of these, the 8-bit Atari is
most similar to the Commodore 64.

In marketing their computers to the public, Atari always had to contend with
their company history and reputation as a maker of video games.  While the
8-bit Atari computers in their heyday were technically quite comparable if=
 not
superior in the worlds of home and business personal computing, they also=
 live
up to the name "Atari" with a huge library of video games which were often
outstanding for their time.

The 8-bit Atari computers do not use the same cartridges or floppy disks as
any other Atari platforms, such as the 2600 Video Computer System (VCS), the
5200 SuperSystem, the 7800 ProSystem, or the ST/TT/Falcon computers.  All of
these but the 5200, however, do share the same joystick/controller hardware
port.

The 5200 SuperSystem is actually nearly identical to the 8-bit computers
internally, yet cartridges for the 5200 and the 8-bit computers cannot be
exchanged, primarly due to the physically different cartridge ports.

Here are some of the performance specifications of the 8-bit Atari=
 computers:

(Some of the rest of this section by Bill Kendrick)

CPU: 6502 (MOS Technology)

CPU CLOCK SPEED:
  NTSC machines:     1.7897725 MHz
  non-NTSC machines: 1.773447 MHz

SCREEN REFRESH RATE:

  + require the GTIA chip.  1979-1981 400/800's shipped with CTIA
 ++ Not available via the BASIC GRAPHICS command in 400/800's.

GRAPHICS INDIRECTION (COLOR REGISTERS AND CHARACTER SETS):
Nine color registers are available.  Each color register holds any of 16
luminances x 16 hues =3D 256 colors.  (Four registers are for player-missile
graphics.

Character sets of 128 8x8 characters, each with a normal and an inverse=
 video
incarnation, are totally redefinable.

PLAYER-MISSILE GRAPHICS:  (byte height and OR corrections from Piotr Fusik)
  Four 8-bit wide, 120 or 240 byte high single color players, and four
    2-bit wide, 120 or 240 byte high single color missiles are available.
    A mode to combine the 4 missiles into a 5th 8-bit wide player is also
    available, as is a mode to OR colors or blacken out colors when players
    overlap (good for making three colors out of two players!)  Players
    and missiles have adjustable priority and collision detection.

DISPLAY LIST INTERRUPTS (DLI's):
  Screen modes can be mixed (by lines) down the screen using the Display
    List - a program which is executed by the ANTIC graphics chip every
    screen refresh:

  All other screen attributes (color, player/missile horizontal position,
    screen width, player/missile/playfield priority, etc.) can be ajusted
    at any point down the screen via DLI's.

SCROLLING:
  Fine scrolling (both vertical and horizontal) can be enabled on any
    line on the screen.

SOUND:
  Four voices of 8-bit pitch-resolution, 4-bit volume-resolution,
    8-distortion sound can be produced.  2 voices (1 and 2, and/or 3 and 4)
    can be combined to make 16-bit pitch-resolution.  Also 4-bit volume-only
    modes can be enabled for digitally sampled sound replay.

  A fifth "voice" is produced by the internal speaker on Atari 400/800's
    (for keyclick and buzzer) and in the XL's and XE's this was
    (fortunately!) rerouted through the normal audio output, and the
    keyclick can be disabled.

Subject: 1.2) What is the Atari 400?

Released along with the 800 in 1979, the 400 was the low-end model of the=
 two.
The only 8-bit Atari with a membrane keyboard rather than a full-stroke
keyboard.  One of the few 8-bit Ataris lacking a composite monitor port.=20
Originally released with just 8K RAM, but most were sold with 16K RAM. =
 Atari
sold the Atari 400 48K RAM Expansion Kit, which required a little soldering,
to dealers only.

Only the 400 and 800 8-bit Atari models have four controller (joystick)=
 ports.

Early 400 units include the CTIA chip; later units include the GTIA chip,
also present in all later 8-bit Ataris.

The 1982 Atari catalog calls the 400 "The Basic Computer".

The 400 was discontinued in 1983.

During development the 400 was known internally as "Candy."

------------------------------

Subject: 1.3) What is the Atari 800?

Released along with the 400 in 1979, the 800 was the high-end model of the
two.  The 800 is the only 8-bit Atari with a Right Cartridge slot, in=
 addition
to the Left Cartridge slot as present on all 8-bit Ataris.  Originally
released with just 8K RAM, many were sold with 16K, later on 48K was=
 standard.

The 800 is also the only 8-bit Atari with a four-slot modular design, where
the first slot holds the CX801 (CX801-P for PAL machines) 10K ROM module,=
 and
the other three slots hold combinations of CX852 8K or CX853 16K RAM=
 modules.

Only the 400 and 800 8-bit Atari models have four controller (joystick)=
 ports.

Early 800 units include the CTIA chip; later units include the GTIA chip,
also present in all later 8-bit Ataris.

The 800 was discontinued in 1983.

During development the 800 was known internally as "Colleen."

------------------------------

Subject: 1.4) What is the Atari 1200XL?

Released as a big brother to the 400/800 in 1982, the 1200XL now uses=
 Atari's
slightly customized 6502C microprocessor, and includes a full 64K RAM.  The
1200XL was the first 8-bit Atari with just 2 controller ports.  In addition,
the 1200XL includes 4 programmable Function keys and a Help key, 4 LEDs,
built-in diagnostic and graphics demonstration programs, and probably the
favorite keyboard of any 8-bit Atari computer.  Clicks previously outputted
through the built-in speaker are now heard from the television or monitor's
speaker.  The revised 16K Operating System offers many new features,=
 including
an alternate International Character Set.

The 1200XL was the biggest single step forward in development of the 8-bit
Atari platform, but the corresponding software compatability problems hurt
its popularity.

The 1200XL lacks separate chroma video signal, and also lacks the +5 Volts
power on pin 10 of the SIO port.

The 1200XL was discontinued in 1983.

------------------------------

Subject: 1.5) What is the Atari 600XL?

Released in 1983 as a replacement for the 400, the 600XL is the low-end
version of the 800XL. The 600XL/800XL include most of the features of the
1200XL minus the Function keys and the demo program.  But both the 800XL and
600XL have the Atari BASIC language built-in.  In addition, these two=
 systems
offer the Parallel Bus Interface (PBI), providing fast parallel access to=
 the
heart of the computer.  The 600XL has 16K RAM.

The 600XL can be expanded from 16K to 64K with the Atari 1064 Memory Module.

Rarely, some late-model 600XLs were sold with 64K RAM.  These may have only
appeared in Canada.  The box had a round gold foil sticker reading:
"64k Memory -- Now with a full 64k of memory built-in."

Normally boots with Atari BASIC (Revision B) enabled;
Hold down [Option] on startup to boot without BASIC.

The North American/NTSC 600XL does not include a composite monitor port;
The European/PAL 600XL includes the monitor port, but this lacks the chroma
video signal.

The 600XL was discontinued in 1985.

------------------------------

Subject: 1.6) What is the Atari 800XL?

Released in 1983 as a replacement for the 800 and 1200XL, the 800XL is the
high-end version of the 600XL. The 600XL/800XL include most of the features
of the 1200XL minus the Function keys and the demo program.  But both the
800XL and 600XL have the Atari BASIC language built-in.  In addition, these
two systems offer the Parallel Bus Interface (PBI), providing fast parallel
access to the heart of the computer.  The 800XL contains 64K RAM.

Normally boots with Atari BASIC (Rev. B, or late models with Rev. C)=
 enabled;
Hold down [Option] on startup to boot without BASIC.

The 800XL lacks separate chroma video signal (exeception next paragraph).

There was a late version of the 800XL in Europe, called 800XLF.  The 800XLF
includes a redesigned motherboard (the XE design) and contains FREDDIE
for memory management and has chroma output.  BASIC is Revision C.

Though Atari never disclosed sales figures, the 800XL was likely the most-
sold of all 8-bit Atari computer models.

The 800XL was discontinued in 1985.

------------------------------

Subject: 1.7) What is the Atari 65XE?

Released in 1985 as a replacement for the 600XL, the 65XE is the low-end
version of the 130XE.  The 65XE is nearly identical to the 800XL in=
 features,
minus the PBI.  Many European (PAL) 65XE's include the ECI port, but no=
 North
American (NTSC) 65XE's include the ECI port.  All XE computers also include
the FREDDIE memory management chip.

Subject: 1.8) What is the Atari 130XE?

Released in 1985 as a replacement for the 800XL, the 130XE is the high-end
version of the 65XE.  The 130XE offers 128K RAM, plus the FREDDIE memory
management chip, supporting the unique (but rarely used) ability for the=
 6502
and the ANTIC to independently access RAM banks.  In addition, the 130XE
replaces the PBI port with the Enhanced Cartridge Interface (ECI),=
 continuing
the powerful feature of a fast parallel port.

1987.  Despite its label, the XEGS is a true 8-bit Atari computer system. =
 It
offers the convenience of a detachable keyboard and built-in Missile Command
game, while offering 64K RAM and full compatibility with the 65XE.  It was
packaged with the Light Gun, and the Flight Simulator II and Bug Hunt
cartridges.

Subject: 1.11) What are the 6502, ANTIC, CTIA/GTIA, POKEY, and FREDDIE=
 chips?

Some of the following text is taken from De Re Atari (Atari#APX-90008), a=
 book
published by Atari through the Atari Program Exchange (APX) and copyright=
 1982
by Chris Crawford, et al.  See http://www.atariarchives.org/dere/ where the
full text of De Re Atari is now available online.

The internal layout of the Atari 8-bit computer is very different from other
systems.  It of course has a microprocessor (a 6502), RAM, ROM, and a PIA.=
=20
However, it also has three special-purpose (LSI) chips known as ANTIC, GTIA,
and POKEY.  These chips were designed by Atari engineers primarily to take
much of the burden of housekeeping off of the 6502, thereby freeing the 6502
to concentrate on computations.  While they were at it, they designed a=
 great
deal of power into these chips. Each of these chips is almost as big (in=
 terms
of silicon area) as a 6502, so the three of them together provide a=
 tremendous
amount of power.  Mastering the Atari 8-bit computers is primarily a matter=
 of
mastering these three chips.

6502 Central Processing Unit (CPU)
=3D=3D=3D=3D
While the 400/800 models contain a generic 6502B CPU (a faster version of=
 the
original 6502A microprocessor), all of the XL/XE models contain Atari's
customized 6502C chip.

On the Atari, there are two microprocessors, ANTIC and the 6502.  To allow
them to coexist, ANTIC must shut off the 6502, a process called DMA.  The
6502B supports DMA, but in Atari's implementation, it required 4 chips.  The
6502C has an extra line called HALT. It is controlled by ANTIC which uses it
whenever it needs the data/address bus. The HALT line is on pin 35 of the
Atari 6502C and must be pulled high for the chip to work.

ANTIC
=3D=3D=3D=3D=3D
ANTIC ("Alpha-Numeric Television Interface Circuit") is a microprocessor
dedicated to the television display.  It is a true microprocessor; it has an
instruction set, a program (called the display list), and data.  The display
list and the display data are written into RAM by the 6502.  ANTIC retrieves
this information from RAM using direct memory access (DMA).  It processes=
 the
higher level instructions in the display list and translates these
instructions into a real-time stream of simple instructions to GTIA.

Frank Schuster writes (6/1/02):
  the patent for the ANTIC processor:=20
   =20
  U.S. Patent 4,296,476 October 20, 1981 for a "Data processing system with
  programmable graphics generator". Inventors listed: Steven T. Mayer; Jay
  G. Miner; Douglas G. Neubauer; Joseph C. Decuir
 =20
CTIA/GTIA
=3D=3D=3D=3D=3D=3D=3D=3D=3D
CTIA ("Color Television Interface Adapter") / GTIA ("George's Television
Interface Adapter") is a television interface chip.  ANTIC directly controls
most of GTIA's operations, but the 6502 can be programmed to intercede and
control some or all of GTIA's functions.  GTIA converts the digital commands
from ANTIC (or the 6502) into the signal that goes to the television.  GTIA
also adds some factors of its own, such as color values, player-missile
graphics, and collision detection.

Early 400/800 models included CTIA, later 400/800 models and all later 8-bit
Ataris included GTIA.

In BASIC, type POKE 623,64 [RETURN] and if the screen blackens, you have the
GTIA chip.  If it stays blue, you have the old CTIA chip.

By the way, apparently no CTIA-equipped Ataris were shipped to Europe.

Clay Halliwell provides this tidbit:
  A bit of trivia: CTIA 400/800s artifact in blue/green, GTIA 400/800s
  artifact in green/blue, and all XL/XEs artifact in red/blue.

Jerry Jessop explains why French Ataris produce fewer colors:
  I will tell you why it only has monochrome out, because it's SECAM and a
  SECAM GTIA was never produced. The PAL GTIA is used in France and the Lum
  outputs are run into an onboard encoder to produce a "psudo" color=
 depending
  on the Luminance output, composite only. This is why a SECAM VCS or 800=
 has
  nowhere near the same number of colors (16) availible as a PAL or NTSC=
 unit
  (256).

  The FGTIA was never completed as the market size did not warrant the
  expense.  The largest SECAM market is not France but the Soviet Union
  (former) and in 80-84 sales of these items there were not possible.

Frank Schuster writes (6/1/02):

POKEY
=3D=3D=3D=3D=3D
POKEY (means "POT and KEY" as in the paddles and keyboard) is a digital
input/output (I/O) chip.  It handles such disparate tasks as the serial I/O
bus, audio generation, keyboard scan, and random number generation.  It also
digitizes the resistive paddle inputs and controls maskable interrupt (IRQ)
requests from peripherals.

All four of these LSI chips function simultaneously.  Careful separation of
their functions in the design phase has minimized conflicts between the=
 chips.
The only hardware level conflict between any two chips in the system occurs
when ANTIC needs to use the address and data buses to fetch its display
information.  To do this, it halts the 6502 and takes control of the buses."

The USPTO granted U.S. Patent 4,314,236 to Atari on February 2, 1982 for an
"Apparatus for producing a plurality of audio sound effects" - POKEY.=20
Inventors listed: Steven T. Mayer, Ronald E. Milner

FREDDIE
=3D=3D=3D=3D=3D=3D=3D
The 65XE/130XE/800XE/XEGS contain a small additional LSI called FREDDIE, a=
 RAM
address multiplexer.  According to James Bradford, "FREDDIE is a type of
memory controller.  It takes the address and clock from the CPU and
multiplexes it with the appropriate timings and signals to use DYNAMIC=
 memory.
FREDDIE also buffers the system clock crystal and divides it down then feeds
that to GTIA.  The XEGS has a FREDDIE but it doesn't have the extended RAM.
Even if it did, you would still need the chip that does the REAL bank
switching.  It is a small 16-pin chip (Atari/Best Electronics catalog number
CO25953: rev9/page 42).  It gets RAS from FREDDIE, the bank select bits from
PIA, A14, A15 and the 6502 halt signal to control which bank of 8 chips RAS
goes to.  A14 and A15 then go to FREDDIE for the address range of the extra
memory bank (or normal address range with no bank switching).  The=
 ANTIC/6502
select bits in combination with the 6502 halt line, control the switching of
the PIA bank number bits to A14/A15 and which bank of memory RAS goes to. =
 Why
people say FREDDIE does the bank switching is beyond me.  An 800XL can look
like a 130XE with that 16-pin chip installed (That's right NO FREDDIE) and=
 an
extra 8 RAM chips."

And more recently James Bradford has written:
FREDDIE is just a memory decoder and timer. It replaces several chips in the
800XL.  The small chip near FREDDIE does all the bank selection.  CO25953.=
=20
One line from FREDDIE, Ras (or is it cas?) goes to this chip, Halt and the
bank /processor select lines go into this same chip and ras (cas?) comes=
 out.=20
A pin for each bank.  If I remember correctly, refresh also goes into this
small chip. It would be quite easy to make an 800XL work just like a 130XE
with this chip since Ras (Cas?) is required by ALL dynamic RAM.

Subject: 1.13) What issues surround NTSC vs PAL versions of the 8-bit Atari?

Contributors to this section:
Wayne Booth, Graham Thornton, Brent Buescher Jr., Thomas Richter, Jindroush

Some quick definitions first:

NTSC standard: Abbreviation for "National Television Standards Committee"
TV signal standard used in North America, Central America, a number of South
American countries, and some Asian countries, including Japan.
525 lines per frame
60 half-frames per second (interlaced) =3D 60 Hz
Complete frame refreshed 30 times per second

PAL: Acronym for "phase alternation by line"=20
TV signal standard used in the United Kingdom, much of the rest of western
Europe, several South American countries, some Middle East and Asian
countries, several African countries, Australia, New Zealand, and other
Pacific island countries.
625 lines per frame
50 half-frames per second (interlaced) =3D 50 Hz
Complete frame refreshed 25 times per second.

PAL-M: A modified version of PAL, used in Brazil.

SECAM: Acronym for "systeme electronique couleur avec memoire"
TV signal standard used in France, eastern European countries, the former
USSR, and some African countries.
625 lines per frame
50 half-frames per second (interlaced) =3D 50 Hz
Complete frame refreshed 25 times per second.


Now then, how do the differences among 8-bit Atari computers designed for=
 the
different world television signal standards affect users trying to use
software written elsewhere in the world?

The 50Hz vertical refresh frequency of PAL machines translates into more
vertical blank interrupt (VBI) time for demos and other=
 computation-intensive
graphics software, when compared to the time available for VBIs on NTSC
machines with the faster 60Hz refresh frequency.  So PAL demos and games=
 that
won't work on NTSC machines are usually returning from a VBI too late.  Some
also attempt to use more vertical resolution ("longer" display lists) than=
 an
NTSC display can handle.

Note that the reverse is also true.  Software using VBIs will run more=
 slowly
on a PAL Atari than on an NTSC Atari.

Replacing the NTSC ANTIC chip in an NTSC Atari with a PAL ANTIC changes the
screen refresh rate to 50Hz, allowing most of the PAL-only European software
to run on a North American NTSC Atari.  However, make sure your display=
 device
can support a 50Hz PAL signal first!  North American Atari users can also
obtain and use real European PAL Atari machines, with the same caveat
concerning the display device.

Bottom line:
Software written for NTSC machines (North America) will (almost) always work
on PAL machines (Europe), but software designed on PAL machines won't
necessarily work on NTSC machines.

Jindroush contributes: (2/26/02)
Could there be a program which runs on NTSC Atari and not on PAL Atari?
Yes, if it uses some precise timing copy protection (probably based on
vblank timing). Examples of these are Transylvania and The Quest by
Penguin Software.

Thomas Richter mentions another NTSC vs PAL issue:
Another point is that the popular pseudo-colors used in the ANTIC-F=20
(Graphics 8) mode are not colorful at all when displayed on a PAL TV,=
 because
of differences in the color encoding for the TV. The schematics of
the XL computers include however a hack how to change the PAL version to
the NTSC version (the PAL versions include two crystals, one with 5/4th of
the frequency of the other. One is used for the system clock, the other for
the color clock), but I never dared to apply it.

Subject: 2.1) What video display devices can I use with my Atari?

Contributors to channel output variations list:
Jon Levy, Rene de Bie, Sysop Fox-1

Most 8-bit Atari computers put out video signals in two places:

1) Radio-Frequency (RF) signal, either one VHF channel, or two VHF channels
selectable by a switch on the computer.  Variations depend primarily on the
part of the world that the particular version of the computer was desgined
for.

Most North American computers: VHF channels 2-3 switch-selectable.
                               channels 3-4 switch selectable also reported
European computers: VHF channels 3-4 switch-selectable,=20
                    or no switch (what channel?) both reported
UK computers: VHF channel 36, no switch,=20
              or channels 38-39 switch selectable both reported
Australian computers: VHF channel 1 (400/800: channels 1-2 selectable)

Any further clarifications would be appreciated!

Accessories needed:
  a) RF Cable. (RF=3Dradio frequency--video and audio signals in the same=
 line)
     On the 400/800 models, the RF Cable does not detach from the computer.
     The output end of the cable is an RCA male connector.

  b) TV Switch Box.  Includes an RCA female connector for RF signal input=
 from
     the Atari, input connector(s) for your TV attenna and/or cable TV
     company, and 75- and/or 300-ohm VHF output connector(s) for connection=
 to
     the VHF input on the television. (Radio Shack carries a suitable TV
     Switch Box.)

2) A proprietary 5-pin DIN Monitor Jack, which includes two video signals:
  a) Composite video.
  b) Y/C Video, also known as S-Video:
     separate composite luminance (Y) and chrominance (C) signals.

Exceptions among the computer models:
-the 400 and North American 600XL lack the Monitor Jack.
-the XE Game System includes an RCA-style jack in place of the Monitor Jack,
 providing a plain composite video signal only.
-the Monitor Jack on the 600XL, 800XL(most) and 1200XL lacks the separate
 chrominance signal.  (But it exists internally, and can be restored to the
 monitor jack via hardware modification.)

The pinout for the Atari Monitor Jack is in the pinouts sections of this FAQ
list.

The typical Atari Monitor Cable includes the male 5-pin DIN connector on one
end, and two RCA male connectors on the other end.  One of the RCA=
 connectors
will carry the monophonic sound signal, and the other will carry the=
 composite
video signal.  Color composite monitors were common in the mid-80's, but=
 these
days many televisions have an RCA female composite video input connector=
 which
works fine with the Atari.

You may find an Atari Monitor Cable where the video signal carried on the
second RCA connector is not the composite video signal, but the composite
luminance signal.  These cables are for use with monochrome composite video
monitors (usually green or amber).

The ideal Atari Monitor Cable includes 3 RCA male connectors on the output
end, carrying the sound signal, the composite luminance signal, and the
composite chrominance signal.  Only the best composite monitors include
separate chrominance and luminance inputs.  Commodore produced many fine=20
monitors of this type, popular with Atari users.

Lonnie McClure provides this information on suitable Commodore monitors:
  1701, 1702, 1802, CM-141, 1080, 2002, 1902, 1902A*, 1084**, 1084S**
=20
  * The 1902A used a DIN connector for chroma/luma, which makes cabling a=20
  bit more of a problem. The composite and audio connectors are standard=20
  RCA jacks, however.
=20
  ** The 1084 and 1084S had more than one version. Some used the a DIN=20
  connector for chroma/luma connections, like the 1902A, while some used=20
  standard RCA jacks.
=20
  The 1902 and 1902A are very different in appearance. The original 1902=20
  shares the same slightly rounded front case design as the 1080 and 2002,=
=20
  while the 1902A is has a rather square case design, and was manufactured=
=20
  by Magnavox (as were some of the 1084 and 1084S versions).

The separate composite chrominance and luminance signals that the Atari puts
out comprise what the world has since come to call Y/C video or S-video.
S-video connectors are normally Mini4.  It is possible to build a cable, or
purchase several adapters, that can allow you to utilize the separate Y/C
signals generated by the Atari with a television (or other display device)
that provides a standard S-video Mini4 input jack.  This is the ultimate
display option for the 8-bit Atari.  Clarence Dyson has a nice page about
such a project at http://www.wolfpup.net/atari/svideo.html .

Adapters also exist that will take in composite video or s-video, and output=
 a
conversion of the signal as a standard VGA video signal.  These are often
known as a "VGA converter" or "Scan doubler."  With such a device, the 8-bit
Atari can be used with a standard PC VGA monitor.  One such adapter is the
Cheese Video Box, http://www.avtoolbox.com/vd-660.htm .  An earlier popular
device was the JAM!! from AIMS Lab.

SCART =96 an acronym for Syndicat des Constructeurs d=92Appareils=
 Radiorecepteurs
et Televiseurs =96 is a 21-pin universal connecting cable/socket system used=
 for
audio/video components in Europe.  The cables transmit RGB, composite video,
S-Video, mono and stereo sound.  SCART, which is also known as PERITEL,
EURO AV BUS and EUROCONECTOR, is common throughout Europe, particularly in
France, England, Germany, Switzerland, and Scandinavia.  SCART is also very
popular in the Russian Audio Video market.  It is possible to interface the
Atari's composite video signal, along with the audio signal, through a SCART
connector, though there have been few reports of people actually doing this.

Subject: 3.1) What are the Atari 410, 1010, XC11, and XC12 Program=
 Recorders?

The Atari Program Recorders provide storage and retrieval of programs
and data on cassette tape.  In addition to the digital track that stores
computer data, a second audio track is provided to play music or voice
as the program runs.

Data transmission rate: 600 bits per second.
Data storate capacity: 100,000 bytes per 60-minute cassette.
Track configuration: 4 track, 2 channel (digital data and audio track)

410 Program Recorder      =20
- early Japan version had a carrying handle
- most versions made in Hong Kong
- 410a--Taiwan version=20
- built-in SIO cable - must end SIO daisy chain
- power - plugs directly into wall (most versions)
- "410P" version (rare).  Karl Heller writes:
  "It came in the white 410 box with an Atari yellow/orange paper slip
   stating which power supply to use with it."

Subject: 3.2) What other cassette recorders can I use with my Atari?

Firstly Atari themselves put out several models beyond the=
 410/1010/XC11/XC12,
generally only known in eastern Europe:

XCA12 Program Recorder     -in same case as XC12...Poland
CA12 Program Recorder      -in same case as XC12...Poland
    image: http://romualdl.multimania.com/images/atari/ca12.jpg

 Czech/Slovak/Poland
XC13 Program Recorder      -XC12 which was "T2000 ready". =
 Czech/Slovak/Poland

For more information on the Turbo 2000 (T2000) and SuperTurbo modifications=
 to
Atari program recorders, with speeds up 9600 baud, see
http://jindroush.atari.org

Unlike other microcomputer systems of the time, it was very unusual to use
anything but Atari brand program cassette recorders.  One third-party=
 product
released was the:

Compu-Mate, by General Electric (GE, G.E.)
Includes external interface module, a power cord/adapter, and SIO cable.
No second SIO port - must be at end of SIO chain.

Subject: 3.3) How do I run a program from cassette?

To run an Atari BASIC program from cassette:

1. Place the cassette in the recorder.
2. Press REWIND of FORWARD, if necessary, to bring the tape to the position
   where the program is located.
3. Boot the computer to the Atari BASIC READY prompt.
4. There are several possibilities for the next step, depending on how the
   program was saved, and whether you want to run the program or just load
   it into RAM.  Enter one of the following four commands:
   a. CLOAD                       loads programs saved with CSAVE
   b. LOAD "C:"                   loads programs saved with SAVE "C:"
   c. ENTER "C:"                  loads programs saved with LIST "C:"
   d. RUN "C:"                    loads&runs programs saved with SAVE "C:"

] Relative efficiency of the three cassette tape recording techniques:
] CSAVE/CLOAD - most efficient - fastest saves/loads - tokenized files
] SAVE "C:"/LOAD "C:" - middle efficiency - middle speed - tokenized files
] LIST "C:"/ENTER "C:" - least efficient - slowest - straight ATASCII

5. The computer will "beep" as a signal for you to press PLAY on the=
 recorder.
6. Press the RETURN key on the computer keyboard, and the program will load
   into the computer.
7. Press STOP on the recorder when loading has finished.
8. Unless you entered RUN "C:" above, now enter the command: RUN

To run an Atari BASIC or machine language program from cassette upon=
 startup:

1. Place the cassette in the recorder
2. Press REWIND of FORWARD, if necessary, to bring the tape to the position=
=20
   where the program is located.
3. Turn on the computer while holding down the START key.
   But if your computer has Atari BASIC built-in and you're running a=
 machine
   language program, hold down both the START key and the OPTION key.
4. The computer will "beep" as a signal for you to press PLAY on the=
 recorder.
5. Let go of the START/OPTION button(s).
6. Press the RETURN key on the computer keyboard, and the program will load
   into the computer.
7. Press STOP on the recorder when loading is complete and the program is
   running.

Rich Mier professes:
You've been plugging and unplugging the SIO cable with the 1050 power pack
plugged in, right?  That's a no-no.  Most of the time it's Okay, but about 1
in 10, 20 times, it will blow out 'U-1'.  It's a CA/LM 3086 I.C. at the=
 right,
rear of the main board.  A 14 pin DIL chip.  Actually it is an array of 5
transistors.

Unplug the power pack from the 1050, then unplug the SIO cable.  Power can=
 be
ON on the CPU.  The problem has to do with the secondary winding of the=
 Power
Pack.  Remember, the problem only occurs 1 out of 10 - 20 times that you do
it, not all the time.

It doesn't really matter if the 1050 Transformer has power on or off, it
'Might' happen if plugged into the 1050.  It is really bad on 810's.

One thing, if the system has been turned off for, oh say, 5 - 10 minutes it
won't matter.  By then all the capacitors should be bled(sc?) to 0 volts.

Subject: 3.6) What kinds of 5.25" floppy disks can I use with my Atari=
 drives?

Russ Gilbert writes:
If you're talking standard computer store, you can't use those 5 1/4" disks.=
 I
mean you can't use high density disks.  They must be double density to use
with the 1050.  Almost all double density 5 1/4" disks have a hub ring, high
density disks don't have the hub ring.

RHamiIton5 elaborates: (5/12/01)
The Atari 8 drives do not have write heads and circuity which can handle the
type of oxide coating used on the high density floppy media; they cannot=
 write
reliably to them. The hub ring has just become a sort of marker to=
 distinguish
the high density from the standard double density diskettes.

Way back in your apple days of '79-'82, most disks were hubless and only the
really premium brands offered hubs to prevent slippage and out of round
problems; you could even buy little kits for adding you own hub rings.

When the home computer swell really hit around '83 and price wars began, hub
rings became common on good disks and eventually became standard down to
include most generic bargain diskettes.

The introduction of high density 5.25's required a different coercivity (=3D
magnetizability) to get more bits in a smaller space and suitable=
 electronics
to do it. These disks were produced hubless; was it a differentiating label=
 or
just unnecessary because of stronger mylar construction? Anyone?

------------------------------

Subject: 3.7) How can I use a hard drive with my 8-bit Atari?

Atari never produced hard drives for the 8-bit Atari, but a variety of=
 options
have been produced over the years.  No common DOS version was written with
drives the size of hard drives in mind, and very few 8-bit Atari users have
owned hard drives for the Atari.  Yet, if you're serious about it, a hard
drive can make a tremendous addition to your system!

A couple of these options are hard drives designed specifically for the=
 8-bit
Atari computers; the rest are interfaces designed to let you attach an
industry standard SASI, SCSI, or IDE type hard drive.  Customized software
(OS, DOS) is often involved as well.

Larry White contributed to some of these descriptions.

Beyond the above printer models, most any "industry-standard" line printer=
 can
work well with the Atari.  For many years, most printers marketed for home=
 use
could be classified into one of two categories: parallel or serial=
 interface.
Parallel line printers are much more commonly used than serial line=
 printers,
with the Epson MX/FX/LX series defining the market.

The most common way to use an industry standard printer with the Atari has
been to attach it through the 15-pin 8-bit parallel port of the Atari 850
Interface Module or equivalent (such as the ICD P:R: Connection).  One=
 gotcha
here is that the 850's parallel port is DB15, where the PC world ended-up
standardizing on a DB25 configuration.  So you need to find or build a cable
that provides the DB15 connector for the Atari end (and Centronics-type
parallel connector on the printer end) when attaching a standard parallel
printer to the Atari through an Atari 850 or equivalent.

Many 3rd-party disk drives for the Atari (along with the XEP80 Interface
Module) do include a DB25 parallel printer port, rendering the need for an
Atari-specific printer cable unnecessary.

The Atari 850 Interface Module and equivalents also provide standard DB9
serial RS232C ports, permitting use of standard serial line printers with=
 the
Atari.  But this is much less common than parallel, both in the Atari world
and in the industry at large.

Some folks have connected more modern inkjet and laser printers with=
 parallel
connections to the 8-bit Atari with success.  Graphics printouts from the
Atari may be less than ideal (look for a printer with an Epson MX/FX/LX
printer series emulation mode), but these types of printers should work fine
for plain text output if they can handle simple line print jobs.  Anyone=
 want
to contribute their experiences to be included here?

Bob Woolley wrote on Sun, 14 Apr 2002:
  I use HP LaserJet 4Ps on my Ataris. They are one of the last front panel
  selectable cheap printers - from which you can select your default fonts,
  etc. The newer laser printers can only set fonts and operating modes thru
  the interface, not impossible, but not as easy as selecting on the panel.
  This does allow you to print just about any point size of the internal
  fonts in the printer on your Atari.=20

  Either way, you really have to do a little work to get properly formatted
  output from a word processor. I have managed to use the proportional font
  setting with AtariWriter and printer driver creation utilities to get good
  results.

Subject: 5.1) What are the Atari 830, 835, 1030, XM301, and SX212 Modems?

A MODulator/DEModulator translates digital information from your computer=
 into
acoustic tones that can be sent and received, from modem to modem, via
standard telephone lines.

Atari produced several modems for use with the 8-bit Atari computers:

Atari 830 Acoustic Modem:    ( =3D Novation 'CAT' )

Beyond the above modem models, most any "industry-standard" external serial
modem can work well with the Atari.  These have been commonly sold for PCs=
 for
many years.  The Hayes Smartmodem more or less defined the market for these,
initially.

One common way to use an industry standard external serial modem with the
Atari is to connect it to the SIO port via an Advanced Interface Devices
(A.I.D., later Supra) R-Verter Serial Bus Modem Adapter cable, or=
 equivalent.

The other common way to use an industry standard external serial modem with
the Atari is to attach it through the 9-pin RS232C serial port of the Atari
850 Interface Module or equivalent (such as the ICD P:R: Connection).  One
gotcha here is that the serial port on the 850 is DB9 female, where the PC
world ended up standardizing on a DB9 male connector for this purpose.  But
gender converters are readily available.

For using modems at speeds of 2400 bps and up with the Atari, it will be
useful to have an understanding of data flow control.  Here is a definition
of flow control from www.modems.com:

 Often, one modem in a connection is capable of sending data much faster=
 than
 the other can receive.  Flow control allows the receiving modem to tell the
 other to pause while it catches up.  Flow control exists as either=
 software,
 or XON/XOFF, flow control, or hardware (RTS/CTS) flow control.  With=
 software
 flow control, when a modem needs to tell the other to pause, it sends a
 certain character, usually Control-S.  When it is ready to resume, it sends=
 a
 different character, such as Control-Q.  Software flow control's only
 advantage is that it can use a serial cable with only three wires.  Since
 software flow control regulates transmissions by sending certain=
 characters,
 line noise could generate the character commanding a pause, thus hanging=
 the
 transfer until the proper character (such as Control-Q) is sent.  Also,
 binary files must never be sent using software flow control, as binary=
 files
 can contain the control characters.  Hardware, or RTS/CTS, flow control=
 uses
 wires in the modem cable or, in the case of internal modems, hardware in=
 the
 modem. This is faster and much more reliable than software flow control.

Some 2400 bps modems, and probably all modems with 9600 bps speed=
 capabilities
and up, normally use V.42 standard error correction and V.42bis standard=
 data
compression.  But V.42 requires either software or hardware flow control,=
 and
V.42bis requires hardware flow control (and V.42 error correction).

Hardware flow control is not available with the Atari 850's serial ports.

As a result, just before dialing out with your Atari telecom software, it's
usually desirable, if not necessary, to disable your modem's flow control.

The Hayes modem command to disable flow control looks like:
     AT&K0

The top speed of the Atari 850's serial ports is 9600 bps.

Clay Halliwell offers a tip on utilizing 9600 bps through the 850 Interface:
 On 11 Feb 1996, Marc G. Frank said:

 > I'm having problems getting a modem attached to my Atari 850 to
 > communicate at 9600 baud.  When I set my communications program to 2400
 > baud, everything works fine.  However, when I set it to 9600 baud, the

 The problem with the 850 is that some of them (like mine) don't produce a
 PERFECT 9600 baud signal.  As a result modems can't train on it, and while
 they will echo characters back, for some nitpicky reason they won't pick up
 on the "AT" attention code.

 The solution is to do all your dialing at 2400 baud, but set the S37
 register to force the modem to try to connect at 9600.  Then switch your
 Atari to 9600 after connecting.
    =20
Through the use of an ICD MIO or a CSS Black Box, it is possible to utilize
modems at speeds up to 14.4 Kbps (V.32bis) at full speed with no loss of=
 data.
The serial R: device handler for the Black Box supports hardware flow=
 control
natively.  Optional for the Black Box, but essential for the MIO, is the
HyperSpeed handler by Len Spencer.

Subject: 6.1) What is the Atari 850 Interface Module?

While the Atari's SIO and controller ports did not conform to established
industry standards, Atari produced the 850 Interface Module to address this
issue.  The 850 connects to the SIO port on the Atari, and provides:

- four 9-pin serial EIA RS232C ports
- One 15-pin 8-bit parallel Centronics-type port

Many "industry standard" (of the time) printers, modems, and various other
devices can be used with the Atari computer in combination with an 850
Interface Module.

Early 850's are in an all metal (black) case, but most are in a plastic=
 beige
case matching the 400/800 computers.  Other features:
- programmable baud rate on any port, including:
  75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, and 9600 bps;
  baudot speeds of 60, 66, 75, 100 words per minute
- uses standard ASCII. Baudot support for radio-teletype (RTTY).

Because the 850 was relatively expensive, provided more capabilities than=
 the
average user was looking for, and was at times unavailable from Atari=
 despite
high demand, there were many 3rd-party interfaces designed to provide some
compatible subset of the 850's features.  Perhaps the most prominent example
of such a product is the P:R: Connection from ICD.

Subject: 6.2) What is the Atari XEP80 Interface Module?

This text written by Thomas Raukamp.

Since the development of the Atari 8-bit line of computers in 1979, users
wanted better text displays than the default 40x24. There has been some
attempts to satisfy this need, like the Austin-Franklin board or the Ace
80/80xl cartridge. For more informations about these modifications read The
Atari 8-bit Hardware Upgrade FAQ from David A. Paterson.
=20
The Atari XEP80 Interface Module is Atari's entry to the 80 column field. It
lets a XL, XE, 400 or 800 computer system display a full 80 columns across
your monitor screen. The XEP80 provides a 256-character wide by 25-line
display window. Up to 80 characters are displayed horizontally at once, and
you can scroll horizontally all the way to the 256th character, depending on
the application you're running. The XEP80 is connected to your system via a
joystick port.
=20
The XEP80 Module interprets commands from the computer for screen display or
output to a printer. The module is supplied with an industry-standard 8-bit
parallel port  so you can connect a parallel printer to your Atari 8-bit (I
even use a HP LaserJet IV on my 130XE ;) ).
=20
All programs that use the standard screen call (E:) should be compatible=
 with
the XEP80 Module. The software provided by Atari supports a 320x200 graphics
mode - this mode only support direct bit images. Note that you can't use all
of the standard graphic capabilities of the Atari anymore.
=20
Although Atari recommends a monochrome monitor for usage with the XEP80, it
runs fine with any type of composite monitor. The output looks great on my
Commodore 1084 for example.
=20
Along with the module comes a software-package containing an AUTORUN.SYS=
 file,
which is the XEP80 handler. If you want to use the module with an=
 application
that is compatible with the XEP80, which has it's own AUTORUN.SYS file, you
can append the application's AUTORUN.SYS on the module's AUTORUN.SYS.

Subject: 6.4) What "vaporware" computers/peripherals were never released?

Atari was a HUGE company, dominating Silicon Valley, and included a massive

Subject: 6.5) What are the power requirements for my Atari components?

Thanks to Matthias Belitz for the European
data in this section.  I need more international help!

As with the rest of this FAQ list, please let me know if any of this
information conflicts with the units you have.

The most important information is the voltage (in volts) required, and
whether you need a transformer (AC output) or an adapter (DC output).=20
The power (in voltamps or watts) and current (in amperes) specifications
of the original equipment as presented here should be regarded as
minimum values.  Higher-than-specified power and current capacities are
entirely usable, and often preferable because such supplies run cooler
and last longer.

Direct Current (DC):
Power (in watts) =3D current (in amps) * voltage (in volts)

Alternating Current (AC):
Apparent Power (in voltamps) =3D current (in amps) * voltage (in volts)
Effective/True Power (in watts) =3D current (in amps) * voltage (in volts)

Subject: 6.6) What graphic tablets were produced for the Atari?

This section by Andreas Magenheimer.

- Atari Touch Tablet by Atari (came with Atari Artist cart., Micro
  Illustrator compatible),
- Koala Pad by Koala Industries (came with Koala/Micro Illustrator
  cart.);
- Powerpad by Chalkboard Inc. (came without software!); the following
  carts were available separately for the Powerpad: Micro Illustrator,
  Leo's Lectric, Micro Maestro, The Programmers Kit, Logic Games, Bear=20
  Jam (as refered to Antic, September 1984);
- Animation Station by Suncom (came with Micro-Illustrator cart.);

------------------------------

Subject: 6.7) What lightpens were produced for the Atari?

This section by Andreas Magenheimer.

- Atari Lightpen (came with Atari Graphics cart.; it produces pictures
  with 127 sectors in length, thus not Micro-Painter, nor Micro-
  Illustrator compatible; however appropriate converter programs can be
  found in the public domain, e.g. the Rapid Graphics Converter);
- Edumate Lightpen (came with a disk with 6 Basic programs; a program
  called Peripheral Vision was available separately from Future House);
- Tech-Sketch-Lightpen (came in two versions: a) the cheaper version
  which included a disk with Basic programs only and b) the more expensive
  version which included the disk with Basic programs and the Micro-
  Illustrator cartridge);
- MC-Pen-Lightpen (came with a disk with 4 Basic programs);
- Reston Lightpen (came with ???);

Note: these infos were taken from Antic, September 1984; I am not sure,
if all these items were really available as listed...

------------------------------

Subject: 6.8) What lightguns were produced for the Atari?

This section by Andreas Magenheimer.

- Atari LG-1 Lightgun (came in two versions: a) complete with XEGS,
  keyboard, joystick, power supply, tv-cable, Lightgun, FS II cart and
  Bug Hunt cart all in one package and b) in a separate package,=20
  containing the Lightgun and the Bug Hunt cartridge); thats's why Bug=20
  Hunt does not have its own package, it was always included with the=20
  Lightgun package and/or the complete XEGS package...
- BEST Lightgun by Best Electronics (a sort of selfmade (?) Lightgun);
- Sega-Lightgun (normally not Atari compatible; but can be converted
  into an Atari compatible lightgun easily);
- other lightguns (most of these have to be converted)...

Note: After having 3-4 Atari and at least one (converted) Sega lightgun,
it is my personal impression, that the Atari lightgun merely works ok=20
on/with TV-sets (and not at all with a monitor), whereas the Sega lightgun
works alright on TV's and (most) monitors. Since I never had a Best
lightgun I cannot comment on this one... (Andreas Magenheimer);

Subject: 6.9) What paddles were produced for the Atari? =20

This section by Andreas Magenheimer.

- Atari Paddles (usually a pair of Paddles);
- Telegames Paddles (available as a) a single paddle and b) a pair=20
  of paddles);
- Reston Paddles (available as a) a single paddle and b) a pair=20
  of paddles);
- and many others...

Note: Both single and duo (pair) paddles are compatible to each other,
using only one port-connector (only one joystick port). Thus, with a pair=20
of paddles you can connect up to 4 paddles (2 pairs) to the XL/XE models
and up to 8 paddles (4 pairs) to the Atari 400/800 models.

Subject: 6.10) What voice/sound synthesis hardware was produced for the=
 Atari?

This section by Andreas Magenheimer.

- Voice-Box II by The Alien Group (a software and hardware package);
- 1400XL/1450XLD Voice Synthesizer (built-in chip inside the extreme rare
  Atari 1400XL/1450XLD models);
- Talk is Cheap by Ed Stewart, Antic Volume 2 Number 4, July 1983,
  pages 64-66; hardware schematics only (a test/demo program is
  mentioned in the text, but not printed in the magazine!);
- Cheap-Talk by Lee Brilliant, Analog Computing, issue 29, April 1985,
  pages 59-67; hardware schematics and software demos, for example=20
  "First Words");
- many other voice synthesizers (mostly selfmade and based on a chip by=20
  National Semi Conductor);

------------------------------

Subject: 6.11) What sound-digitizers/samplers were produced for the Atari?

This section by Andreas Magenheimer.

  (german Atari magazin 1/1989, pages 44-49, complete with schematics,
   documentation, sample-program and assembler-source);
- Alphasys-Sound-Sampler cart. (4-Bit) by ANG/Mirage (released as a mono
  version; a stereo (two Pokeys!) version was promised/planned, but afaik
  never released);
- ARGS-XE-Sampler (8-Bit) by ABBUC regional group ARGS (only one or
  two prototypes exist, alas the hardware was never released due to lack
  of (sampling/digitizing) software; maybe a good idea for the hardware
  and software experts out there!);
- and many others ...

------------------------------

Subject: 6.12) What sound-enhancement upgrades were produced for the Atari?

This section by Andreas Magenheimer.

a) enhancements for stereo-sound:

- POPS, polyphonic-pokey-sound by Lee Brilliant (stereo-support with one
  Pokey!); refer to Analog Computing, issue 66, november 1988, pages=20
  54-60; only 1-2 programs exist for this mod., see: 8.14 stereo-software
  for the Atari;

- stereo with two Ataris (and thus 2 Pokey chips); use computer/pokey 1
  for the left channel and computer/pokey 2 for the right; no special
  hardware required for this trick (but specially programmed software!);
  see also: 8.14 stereo-software for the Atari;

- stereo with 2 Pokey chips (in one Atari!); refer to an article written
  by Chuck Steinman (which probably appeared in Atari classic?) on how=20
  to upgrade your Atari internally with a second Pokey chip; or ask=20
  Freddy Offenga for a deluxe-stereo-version, that uses a PCB instead of=20
  the piggy-back method. For a list of software that supports this mod.=20
  see also: 8.14 stereo-software for the Atari;

- Stereo-Blaster and Stereo-Phaser by Portronic/AMC-Verlag, these were
  hardware add-ons that connected via the monitor jack to the Atari and
  gave you "another" monitor jack and 2 cinch connectors to connect to
  the monitor and/or the hifi-system; various small paddles (4-10,
  depending on the model you have) make it possible to change amplitudes,
  frequencies, etc. and thus generate a "pseudo-stereo" sound. These
  add-ons also amplified the sound and thus made quality recordings of
  Atari sounds much easier. Alas, these hardware add-ons were quite
  expensive and thus not many (less than 100) were sold. Therefore no
  special software is required, every A8 sound can be changed or=20
  enhanced to "simulated-stereo"...

- Stereo-Blaster-Pro, a hardware add-on by Portronic/AMC-Verlag similar
  to Stereo-Blaster and Stereo-Phaser, but programmable! This add-on had
  only 1 small paddle, to amplify the sound-volume; the stereo-sound=20
  could be generated via two simple Poke-Statements, a demo-disk therefore
  was included. Alas, not many items were sold and afaik no-one else=20
  programmed stereo-software for it. See also: 8.14 stereo-software for
  the Atari...

b) other sound enhancements:

- Covox-Sound-Enhancement, originally developed in Poland; with some =20
  electronic parts and pieces you can upgrade your Pokey's abilities, to =20
  playback any digitised/sampled sound with 8-Bit resolution, instead of =20
  its usual 4-Bit digi/sample playback resolution (see also 8.14).=20
 =20
- SID-upgrade, the SID is the standard sound-chip in the C64 computers.
  Some polish freaks/nerds have found a way to include it into an A8,
  but allthough I have seen quite a lot of pictures (for example at=20
  atariarea.nostalgia.pl) with this mod. and already found 1 or 2=20
  programs that detect it (for example System Info 2.x by Draco), I=20
  have not yet found any schematics for this upgrade. Anyway, it exists,=20
  and with some programming skills it would surely be possible to write=20
  programs then, that playback SID sounds on those Ataris which have this=20
  upgrade installed...=20

- Amie/Amy sound-chip, the Amie sound-chip was originally produced by
  Atari and installed into the 65XEM computer. Alas, it was never
  available to the public and only very few prototypes of this 65XEM=20
  (maybe less than 10?) do exist. Besides of that RUMOURS say, that
  Atari had quite some problems with this soundchip and never finished=20
  it completely/successfully. If the rumours are true, then this=20
  soundchip provided many more sound channels, more octaves and even=20
  more and better sound power than two Pokeys together (for more infos=20
  take a look at this URL:     )

- guess there are dozens of other sound enhancements, for example sound
  cards (like Adlib, etc.), sound-chips, midi-interfaces, etc. that could
  be attached or converted to the A8; I won't name them all here...(A.M.)

------------------------------

Subject: 6.13) What MIDI enhancements are there for the Atari?

This section by Andreas Magenheimer and Mathy van Nisselroy.=20
=20
Midi is standard on the Atari ST computers, because it is built-in into=20
these computers. Nevertheless, Midi was long before the arrival of the=20
ST computers on the market and thus, it is no surprise that there are=20
even midi-interfaces and enhancements for the classic 8Bit Ataris. The=20
following "types" do exist:=20
=20
- "Midi-Mate" and "Midi-Track" by Hybrid Arts (USA), comes with hardware=20
  + software, see reviews & tests in Antic, Analog and other magazines.=20
  MidiTrack requires 48k RAM, MidiTrack II 64k RAM and MidiTrack III=20
  128k RAM (XE compatible, not Axlon compatible). MidiMate features=20
  MIDI IN+OUT and SYNC IN+OUT ports, but lacks a second SIO plug.
  MMS (MIDI Music System) is a MIDI version of AMS, also sold by Hybrid=20
  Arts and comes with AMS to MMS converter software...

- "MIDI Master" by 2-Bit Software (UK), comes with hardware+software.
   Features MIDI IN+OUT ports, an extra SIO plug, but no SYNC ports.
   See also reviews and ads in (New) Atari User...

- "MIDI interface" by DIGICOMM (UK), comes with hardware + 'example
  programs'. Features MIDI IN, THRU and OUT ports. There`s no word
  about a second SIO plug or any SYNC ports. See also reviews and ads
  in (New) Atari User...

- "MIDIMAX" by Wizztronics (UK), comes with hardware and software.
  Features MIDI IN+OUT ports and a second SIO plug. The MMS software=20
  that comes with MidiMax requires 48k RAM and is fully compatible to=20
  the Hybrid Arts hardware+software. This means, one can use the=20
  software with both Midi-interfaces or use the interfaces with the=20
  software of both vendors...

- "Atari-Midi-Interface" by Karlheinz Metscher (appeared in the german=20
  magazine Computer Kontakt June/July 1986, pages 69-75, complete with=20
  documentation, schematics and its first program "Midi-Receiver";=20
  in Computer Kontakt October/November 1986 appeared the second program,=20
  called "Midi-Disk" - a Midi Recorder and Player program);=20
=20
- "Midi-Interface for Atari XL/XE" by Ireneusz Kuczek (appeared in the=20
  german ABBUC magazine, issue 65, pages 3-6); the paper-mag. includes=20
  a schematic for the midi-interface and some translated descriptions for=20
  the software (translated from polish to german language), whereas the=20
  disk-magazine contains the midi-programs "Midiplay Version 1.3" by I.=20
  Kuczek, "Midi-Recorder Version 1.2" by I.Kuczek, "Rec to Mid" by I.=20
  Kuczek (a converter program for the IBM-PC!), "Midi-Sequencer V.1.15"=20
  by Maciej Sygit and "Midi-Pattern-Editor MPE V.2.3" by Radek Sterba.=20
  These programs and many additional demo sounds are also available in=20
  the ABBUC PD library (PD numbers 625-632).

- guess there are several other (selfmade) midi-interfaces for the Atari=20
  8Bit available, alas they also require a keyboard or synthesizer and=20
  self-created (or downloaded) midi-sounds can only be played back via=20
  such a midi-interface and the affore mentioned keyboard/synthesizer.=20
  As of yet, it seems there exists no midi-player program, that can=20
  playback any midi-sound via the Atari Pokey chip, nor any converter=20
  program, which can convert *.MID sounds into other Atari sound formats=20
  (that could be played back on the Atari then)...=20

------------------------------

Subject: 6.14) What graphics enhancements are there for the Atari?

This section by Andreas Magenheimer.

- some 80 column interfaces made by Atari and third parties. Allthough=20
  these interfaces are there to provide a better text display with 80=20
  chars. per line, they can somehow be used as a simple graphic=20
  enhancement; think I have seen a graphic demo for the XEP-80 device=20
  somewhere, that used a higher graphic resolution in Gr. 0 or Gr. 8=20
  and also provided some animation (not only text, but also graphics),=20
  alas I don`t remember the name of that demo...;
- the ultra-rare 1090XL box and probably graphic cards for it (who-ever=20
  owns this item, doesn't use it, who-ever would like to have + use it,=20
  doesn't own it or cannot afford it!);
- more seriously: Antic and GTIA upgrade by Chuck Steinman. Afaik, an
  article about that topic appeared in Atari Classic, since I do not own
  it, I can merely speculate that it adds a second Antic and GTIA for=20
  higher resolution and/or more colours...;
- many selfmade upgrades, using graphic chips or graphic cards from other
  computers...

------------------------------

Subject: 6.15) What types of memory upgrades are there for the Atari?

This section by Andreas Magenheimer.

Just a short overview here, for a more detailed description (table), see
also 8.10 kinds of atari ramdisks (and 8.11 + 8.12 for programs that
support or require a ramdisk). The following memory enhancements do exist:
- Atari 400/800: ramdisks on memory boards, that fit into the normal=20
  Atari 800 memory slots (Axlon and Mosaic types);
- Atari XL/XE: a) internal memory enhancements:=20
  - piggy-back versions,
  - professionel PCB versions,
  - SIMM-module versions;
               b) external memory enhancements:=20
  - via XL-Parallel-Bus,=20
  - via XE-Cart.port+ECI,=20
  - Flash-ROM cart. versions,=20
  - other Cartridge versions,=20
  - RAM-Card versions,=20
  - SIO-cartridge versions,=20
  - ...               =20
Note that many of these XL/XE memory enhancements are just hobbyist or
selfmade-projects. Most versions which use newer PC technologies
(Flash-ROM cart., RAM-Card, SIO-cart., etc.) are still under development!

------------------------------

Subject: 6.16) What networking hardware is there for the Atari?

This section by Andreas Magenheimer.

In the late 80`s and early 90`s an american "firm" called Dataque
developed some networking-computer-hardware to link two or more Ataris
together, so that multiplayer games are possible, where each user has
its own computer and tv/monitor screen. The hardware was/is computer
independant and will run fine on any Atari 8Bit computer (whereas most
software for it will only work on XL/XE computers). During a 3-4 year
period of development two different hardware add-ons were developed:

a) Gamelink-1: This hardware was developed in 1989/90. It links two
   computers together via the joystick ports. It is limited to a maximum
   of 2 computers and thus 2 or 6 players, meaning one free port per
   XL/XE computer and 3 free ports per 400/800 computer. However, the
   few existing games for this hardware merely support 2 players, no
   matter, which computer you have...

b) Gamelink-2: This hardware was developed in 1991/92. It links 2 to 8
   computers together via the SIO-port. One computer will then act as
   the master and has to boot up the software (from tape, disk, harddisk,
   etc.) first. Then all other "slave" computers connect to it and boot
   off of this master computer (one after another of course). In Europe
   we call this device "Multilink", mostly because of the games written
   by Bewesoft (Jiri Bernasek) called Multi-Dash, Multi-Race, Multi-Worms.
   A two-computer link-network can easily be done with one SIO cable, just
   open the end of the SIO cable and exchange cables number 3 and 5. You
   now have an easy two-computer (2-4 players) network-cable.
=20
For some available software, that supports this networking-computer
hardware, see 8.16 which programs support networking computer hardware...

------------------------------

Subject: 6.17) Can I attach an ISA card to the Atari?

Yes, RoBu (Roland Buhler) of the Stuttgart ABBUC Regional Group has produced
project plans for an ISA-Bus Interface for Atari 800XL/130XE Computer, ARGS.
http://www.stud.uni-karlsruhe.de/~un55/Hardware/ISA-Interface/ReadME.html

Carsten Strotmann has released sourcecode showing how to access a Hercules
video card with the ISA-Bus Interface.

BASIC and 8k for Missile Command).


Origins of ROM information
~~~~~~~~~~~~~~~~~~~~~~~~~~
400/800 rev.A NTSC      Could exist, since the PAL version exists and
                        rev.A is mentioned in the rev.B source code.
james adds (3/8/01):
  Did exist!  My parents bought me an Atari 400 w/ 410 back in 1981 for
  entertainment when I was badly injured in a motorcycle accident.  A
  year or so later I paid good money ($40 USD or so?) to have the OS A
  upgraded to OS B.=20
400/800 rev.A PAL       All info found in two Atari 400's and Atari 800
                        ROM module CX801.P
400/800 rev.B NTSC      Information from a ROM dump and the rev.B source
                        listing. The part numbers were listed in the
                        catalog from 'Best Electronics'. According to
                        'Mapping the Atari' rev.B ROMs have a 'B' at the
                        end of the part number, therefore I figure these
                        part numbers are from rev.B.
400/800 rev.B PAL       Could exist, since the NTSC version exists and
                        there's some conditional PAL/NTSC assembly in
                        the rev.B source code
1200XL rev.10 PAL/NTSC  All info found in an Atari 1200XL. The XL/XE
                        rev.2 source code refers to it as rev.10.
                        'Best Electronics' calls it rev.A.
1200XL rev.11 PAL/NTSC  Refered to rev.11 by the XL/XE source code.
                        'Best Electronics' calls it rev.B.
XL/XE rev.1             All info found in an Atari 600XL
XL/XE rev.2             All info found in an Atari 800XL
XL/XE rev.3             All info found in an 800XE

The following OS roms originate from rare Atari 8-bit systems.
Since I don't own any of these (unfortunately), I don't have much
information about these roms. Who can help me?

I've got two 16K rom dumps from the 1450XLD. Both ID's are rev.3.
The first dated 3/23/1984 comes from the 'Pooldisk Too' CD-ROM
(filename: 1540os3.v0) and the second dated 6/21/1984 was send to
me by Nir Dary (filename: os1450.128). Main differences between
these two are in the first 3K ($C000 - $CBFF).

The XL/XE OS rev.3B is from an Atari from Arabia. It's probably based
on rev.3. There are changes in the fonts (Arab characters) and several
patches in the code. More info at:

More info on what is maybe either the 1985 or 1987 XL/XE OS versions listed
above. From ST*ZMAGAZINE #36, Sept. 1, 1989 (as reprinted in PSAN Nov 89):
by Mark Elliot, Innovative Concepts
The following changes have been incorporated in the 130XE computer.

The O.S. has minor changes like:
  A) The MEMORY TEST (from SELF TESTS) tests the extra 64K now! (in 4=
 squares)
  B) Also, the MEMORY TEST checks the first 48K over TWICE as fast as=
 before!
  C) The KEYBOARD TEST has the F1-F4 keys missing on top.  (function keys),
     although the code that interprets them is probably there (like XEGS).
  D) Also, it types out "COPYRIGHT 1985 ATARI" at the keyboard test, when=
 all
     tests are done.  (compared to COPYRIGHT 1983 ATARI, before)
  E) And, the O.S. chip itself, is on a 27256 EPROM, but only half of it is
     used! (comprared to the original, which was on a 16K x 8 ROM, 27128=

Subject: 7.2) What is the ATASCII character set?

ASCII is an acronym for the American Standard Code for Information
Interchange. Pronounced ask-ee, ASCII is a code for representing English
characters as numbers, with each letter assigned a number from 0 to 127. For
example, the ASCII code for uppercase M is 77. Most computers use ASCII=
 codes
to represent text, which makes it possible to transfer data from one=
 computer
to another.

The 8-bit Atari computers use a modified version of the ASCII character set
called Atari ASCII, or ATASCII.

David Moeser produced this nice translation table.
Piotr Fusik corrected the description of Atari character 5.

Subject: 7.3) What is Atari BASIC?

BASIC is an acronym for Beginner's All-purpose Symbolic Instruction Code.
Developed by John Kemeney and Thomas Kurtz in the mid 1960s at Dartmouth
College, BASIC is one of the earliest and simplest high-level programming
languages, incorporating components of FORTRAN and ALGOL.

In 1978 Atari contracted with Shepardson Microsystems, Inc (SMI) to create a
version of BASIC for their upcoming home computers.  The following worked
together on the project, which resulted in Atari BASIC:

Paul Laughton (author of Apple DOS) - project leader, co-primary contributor
Kathleen O'Brien - co-primary contributor
Bill Wilkinson - floating point scheme design
Paul Krasno - implemented the math library routines following guidelines
              supplied by Fred Ruckdeschel (author of the acclaimed text,=20
              BASIC Scientific Subroutines)
Bob Shepardson - Modified IMP-16 Assembler to accept special syntax tables
                 Paul invented
Mike Peters - keypuncher/computer operator/junior programmer/troubleshooter

Three Revisions of Atari BASIC were produced: A, B, and C:
  A - cartridge produced for use with the 400/800/1200XL
  B - built-in to the 600XL/800XL, also produced on cartridge
  C - built-in to the 800XL(late models)/65XE/130XE/800XE/XE Game System,
      also produced on cartridge.

In order to find out what version you are running, at the READY prompt,=20
enter "? PEEK(43234)"

If the result is:  You have Revision:       Atari Part#:
     162                  A                 CO12402/CO14502=20
     96                   B                 CO60302A=20
     234                  C                 CO24947A=20

On versions A, B, and C, Greg Miller writes:
  "Rev A had a number of bugs, not just the commonly described crash bug.=20
  Rev B fixed most (maybe all, I don't remember) of these, but in the
  process, they added a new bug.  You see, the crashes were caused by a bug
  in one of OSS's memory move routines.  When the bug was fixed, the fix
  mistakenly applied to a routine that actually worked in Rev A, causing the
  new lockup problem.
=09
  Rev C differs in only a few bytes. AFAIK, the only change was to remove
  the alteration made to the routine that was broken by Rev B.

Also concerning versions A, B and C, Russ Gilbert writes (3 Jul 2002):
  "I've got an opinion on this, my opinion is wrong to 95% of Atari users.
=09
  B is a re-compile of A.  C is a 12 byte patch to B.
=09
  I've used Atari BASIC for a millenium (?).  B has less hangs and
  ridiculous stuff like losing DIMs and stuff.  C hangs like a lot. I must
  admit I don't have very much experience with C as I go back to B after
  using C for a short time.
=09
  I prefer B.  I know its foibles.  Just LIST, NEW, ENTER, SAVE every 5 or
  6 SAVEs.  Also, 0 REM will help with ENTERs that aren't working (put a
  immediate 0 REM line before you ENTER.)"

Subject: 7.4) What are Atari DOS 1, DOS 2.0S, DOS 3, DOS 2.5, and DOS XE?

Here are short descriptions of the various Disk Operating Systems (DOS)
versions produced by Atari for use with their 8-bit computers.

The original Atari DOS shipped with all 810 disk drives from 1979-1981.  It
consists of a single file, DOS.SYS, which is loaded into memory from disk on
startup.
At the top of the menu screen it reads:
   DISK OPERATING SYSTEM    9/24/79
   COPYRIGHT 1979 ATARI
Unless you are a collector, you probably have no reason to work with DOS 1.
The DOS 1 disk is labeled: Atari 810 Master Diskette (CX8101).

DOS II Version 2.0S was shipped with all 810 disk drives, and early 1050=
 disk
drives, from 1981-1983.  It consists of two files:
DOS.SYS is loaded into memory from disk on startup
DUP.SYS, which contains the DOS menu, is loaded only when needed.  =20
MEM.SAV can be employed to preserve the contents of memory to disk when
DUP.SYS is loaded, so that the data can be restored to memory when exiting
from the DOS menu.  DOS 2.0S supports Atari's proprietary single-sided,=
 single
density 90K 5.25" floppy disk format only.  DOS 2.0S represents the lowest
common denominator of Atari DOS versions--you can be assured than any Atari
disk drive for the 8-bit Atari can work with disks formatted with DOS 2.0S.
The DOS 2.0S disk is labeled: Atari 810 Master Diskette II (CX8104).

DOS II Version 2.0D was shipped with the rare Atari 815 Dual Disk Drive.
Supports double-density disk drives; also supports single-density disk=
 drives.
The DOS 2.0D disk is labeled: Atari 815 Master Diskette (CX8201).

DOS 3 shipped with 1050 disk drives from 1983-1985.  It was created in part
to take advantage of the 1050's Dual-Density capability, by employing a
single-sided, enhanced-density 128K 5.25" floppy disk drive format.  Atari
called this format "dual-density," but the Atari community quickly came to
refer to this format as "enhanced-density" to better differentiate it from
widely available 3rd-party truly double density disk drives and supporting
versions of DOS.  DOS 3 uses a disk format incompatible with DOS 2.0S.  It
included a utility to convert files from DOS 2.0S to DOS 3, but not back
again.  It used disk space less efficiently than DOS 2.0S.  For these=
 reasons
and others, DOS 3 was not widely accepted by the Atari community, and like
DOS 1 is not generally used except for curiosity's sake.
The DOS 3 disk is labeled: Master Diskette 3 (DX5052).

DOS II Version 2.5 shipped with 1050 disk drives and early XF551 disk drives
from 1985-1988.  DOS 2.5 represented Atari's relenting to the masses,
returning to DOS 2.0S compatability.  DOS 2.5 very closely resembles DOS=
 2.0S,
with just a few features added.  It supports both DOS 2.0S single-density=
 90K
formats, as well as an enhanced density 128K format for use with the 1050=
 disk
drive.  DOS 2.5 also includes a RAMdisk utility for use with the 128K 130XE
computer, a utility to convert files from DOS 3 disks back to DOS 2.5, and
other disk utilities.  DOS 2.5 is just about as universal among Atari users=
 as
DOS 2.0S.

DOS XE shipped with XF551 disk drives from 1988-1992.  Like DOS 3, DOS XE
introduced a whole new format for Atari floppy disks; but unlike DOS 3, DOS
XE also preserved general compatability with DOS 2.0S/2.5.  DOS XE supports
the full capabilities of the double-sided, double density 360K per 5.25"
floppy disk XF551 disk drive, including that drive's high-speed burst mode.=
=20
DOS XE also fully supports the 90K SS/SD capability of the 810 disk drive,=
 the
128K SS/ED capability of the 1050 disk drive, the 180K SS/DD capability of
most 3rd-party disk drives for the Atari, and a RAMdisk for use with the
130XE.  Date-stamping of files is supported.  DOS XE requires an XL or XE
computer; it is not compatable with the 400/800 computer models.  Even=
 though
DOS XE was critically well-received, and represented a substantial jump in
capabilities over DOS 2.5, its arrival came so late in the crouded realm of
Atari and 3rd-party DOS versions that it never achieved much acceptance=
 among
real users, and is now relegated to the same status as DOS 1 and DOS 3=
 before
it.  Before its release, DOS XE was widely known as "ADOS."

Subject: 7.5) What are MyDOS, SpartaDOS, and other popular DOS versions?

Section includes contributions by Andreas Magenheimer (most DOS 2 clone
descriptions).

Atari DOS versions are very popular, but many 3rd-party DOS versions have=
 also
been developed over the years.  Of these, MyDOS and SpartaDOS seem to be the
most-used today.

MyDOS 4.53
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
MyDOS is modelled after Atari DOS 2.0S/2.5, but provides subdirectory and
hard-drive support, along with many other "high-end" features.

MyDOS 4.53/3 was released as freeware by David R. Eichel on 1/1/90. =
 Defaults
to a 3 character file length/free sector count instead of MyDOS's normal 4.
Supports multiple AUTORUNs at boot up (*.AR0 through *.AR9).  Supports Axlon
RAMdisks.

MyDOS 4.53/4 is the same as 4.53/3, but uses a minimum of four characters in
the sector count just like most versions of MyDOS.

MYDOS 4.51 was developed by Wordmark Systems (Charles Marslett).  Source=
 code
is available as "abandonware" at: http://www.wordmark.org/

MYDOS 4.50 was released on 11/28/88, developed by C. Marslett & R. Puff
http://www.nleaudio.com/css/files/MYDOS45M.ARC

Mathy van Nisselroy's MyDOS page:
http://www-users.rwth-aachen.de/mathy.van_nisselroy/mydos.htm

SpartaDOS 3.2, 3.3, X (4.22)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D
SpartaDOS is a completely different command-line DOS modelled after MS-DOS,
though it is perfectly capable of reading all Atari DOS and MyDOS disks.

There are many versions available.  Hopefully this list will help keep them
all straight.

SpartaDOS X (SDX) cartridge
---------------------------
Greatly enhanced/expanded compared to disk- based SpartaDOS; completely
different source code. Several versions produced:
    4.22  11-05-95  released by Fine Tooned Engineering (FTe)
    4.21   7-10-89  released by ICD
    4.20   2-06-89  released by ICD
    4.19   1-16-89  released by ICD
    4.18  10-29-88  released by ICD=20
    4.17    ?-?-88  released by ICD

SpartaDOS Pro 3.3a, 3.3b, and 3.3c - 1994-
----------------------------------
The SpartaDOS Pro 3.3 versions were developed by Stephen J. Carden, based=
 upon
a dissembled copy of the older (more stable?) 3.2c release from ICD.
-- SpartaDOS Pro Ver 3.3a  3-Nov-94 -- Added MUX support and MS-DOS=
 Commands.
   Highspeed SIO routines NOT included.  Recommended for use in emulators=20
   (especially Xformer) only.
-- SpartaDOS Pro Ver 3.3b 25-Dec-95 -- Has two different SIOV handlers, one
   for the MUX and one for the MIO.
-- SpartaDOS Pro Ver 3.3c  1995 -- Looks at your system and by checking it
   determines what CIO handler to load, and has MS-DOS command set.  Black
   Box, MUX, and MIO are fully supported, though none of these are required.
-- SpartaDOS Pro Ver 3.3c 19-Dec-97 -- the same 3.3c produced on a 16K ROM
   cartridge by Video 61.
-- SpartaDOS Pro Ver 3.3d -- exists, but is not in general release

According to Lance Ringquist:
K-Products contracted FTe to develop SpartaDOS Pro 3.3 for exclusive use and
distribution with K-Products' BBS Express! Pro, to provide this BBS system
with the most stable platform possible.  As Video 61 now owns the rights to
BBS Express! Pro, SpartaDOS Pro 3.3 is therefore now a product of Video 61.

According to Stephen Carden:
The SpartaDOS Pro 3.3 versions were never owned by K-Products, and are
technically shareware owned by FTe, although FTe had no connection with the
specific development of the 3.3 versions.

SpartaDOS 3.2g and 3.2gx - Dated 6/4/94.
------------------------
Last official disk-based versions, released as shareware by Fine Tooned
Engineering (FTe), who had purchased the rights from ICD.  3.2g is the=
 primary
version; 3.2gx differs only in that it locates the disk buffers under the OS
to save RAM.  3.2gx is intended for use in systems that include a PBI device
(MIO, Black Box); it is not compatible with BASIC XE or any other programs
using RAM under the OS.

First shareware release from FTe: 3.2f.

Earlier major releases from the original developer, ICD: 3.2d, 3.2c, 2.3,=
 1.1.

Only the SDX cartridges and the original version 1.1 are compatible with the
400/800 computer models; SpartaDOS 2.x, and 3.x require an XL/XE.

Many disk-based SpartaDOS versions are available for download here,
Thunderdome, kept by SysOp Fox-1:

BW-DOS 1.30 and BW-DOS Update #2 - Released: 12/95   ("BeWe")
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D
Another popular, powerful DOS is BW-DOS, freeware by Jiri Bernasek. (it is
pronounced "Bay Vay Dos") which is SpartaDOS compatible. Does not use any
speeder internally, but comes with external XF551 speeder. Supports 4 drives
and Ramdisk, comes with Ramdisk driver for XE compatible Ramdisks up to
1Megabyte; supports 4 densities: a) Single (90k), b) Enhanced/Medium (130k),
c) Double (180k) and d) DSDD (360k); does not use any RAM under OS ROM;=
 unlike
SpartaDOS most commands are external, thus the DOS is only 5kbytes short;
supports a PAL clock (made by ABBUC regional group "ARGS"); comes with many
great utilities (which can also be used with SpartaDOS); paper printed=
 German
and disk printed English docs are avaiable; latest version 1.3 is avaiable=
 as
Freeware...

The other DOS varieties mentioned below are all, like MyDOS, Atari DOS-2
clones and thus DOS-2 compatible; avaiable as PD or Freeware...

TOP-DOS 1.5+
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Carolyn Hoglin writes:
This superior DOS was written by R. K. Bennett of Eclipse Software in
Sunnyvale, CA. It was based on Atari DOS, but with many, many more features.
It fully supports my double-density, double-sided Astra drives,=
 automatically
sensing the proper density and sidedness of both drives 1 and 2. (MYDOS only
seemed to do that on drive 1.) Also supported are large ramdisks for Axlon,
Mosaic, etc. The latest version was TOP-DOS 1.5+, which came with an=
 excellent
manual explaining how to use its powerful capabilities.

SuperDOS 5.1
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
supports 4 formats SD/ED/DD/DSDD; supports 256k Xtra RAM/RD; supports 4
speeders: Happy+Speedy+XF551+US Doubler and its compatibles; has an AUX.SYS
file with option to use / not use RAM under OS ROM; has unfortunately a very
slow Ramdisk;

BiboDOS 5.4 and 6.4=20
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
3 versions avaiable, one without speeder - 5.4NT, one with Happy/Speedy
support 5.4HS and one with XF support 6.4XF; supports 4 formats / up to=
 360k;
supports 256k Xtra Ram / RD; the DUP.SYS uses RAM under OS ROM, thus
Turbo-BASIC must load without DUP;

Turbo-DOS 2.1=20
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Master-Disk produces 4 different versions: 2.1NT without speeders, 2.1HS for
Happy/Speedy, 2.1XF for XF551 and 2.1EX for 3 speeders: Happy+Speedy+XF551;
supports 256k Xtra RAM / RD and supports use of batchfiles; has converter=
 for
DOS 3 and DOS 4; supports 4 formats, up to 360k; does not use RAM under OS
ROM; DUP uses a Command Processor; all commands are avaiable via HELP key;
works with XL/XE computers only, does not load/boot on Atari 400/800 no clue
why;

Subject: 7.6) How do I modify Atari DOS to support more than two drives?

Russ Gilbert writes:

DOS 2 type DOSes default to two drives.
Boot DOS and BASIC.
? PEEK(1802)
if it is 3 then you only recognize two drives.
To get the 3rd drive, poke 1802,7.  Then go to dup.sys (type DOS)
and write system files.  Next time you boot that DOS, you'll recognize
3 drives.
If you want four drives, poke 1802,15.

Subject: 7.7) Are there Graphical User Interfaces (GUIs) for the Atari?

Contributors: Andreas Magenheimer, Mathy van Nisselroy, Kathleen Ferrante

- Diamond GOS version 1 (a cart and a PD demo-disk-version do exist),=20
  version 2 (cart only), version 3 (cart only); plus some applications=20
  (painter program, text program, etc.); Diamond GOS has been made=20
  freeware by the author Alan Reeve;

- G.O.S., the Graphic operating system by Total Control systems; two=
 different
versions are avaiable (I call them GOS 1 and GOS 2) and they are PD;

- G.O.E., the Graphic Operating Environment also by Total Control Systems
(this one merely works under Sparta DOS, not with Bewe-DOS and not at all=
 with
DOS 2.x); so far I have found 3 different versions (GOE 1,2,3) with some
applications (graphic/painting program, etc.); PD;

- S.A.M., the Screen Aided Management (unfortunately it has the same name as
SAM, the software aided mouth) from PPP/Germany. It is avaiable in two
different versions: a) the type-in listing from Atari magazin and/or the=
 Lazy
finger disks (which are PD!) or b) the commercial version 2.0 which has many
add-ons and can still be bought from Dean Garaghty/UK or
PD-World-Versand/Germany; This GUI merely works correct under DOS 2.5 and
Medium/dual density, however...

- BOSS-XL, the XL-Desktop from Mirko Sobe; written in Turbo-BASIC; freeware;
http://www.atarixle.de/

- BOSS-XE, the XE-Desktop from Mirko Sobe; written in Turbo-BASIC;freeware,
http://www.atarixle.de/

- BOSS-X the newest desktop version from Mirko Sobe, needs an 128k+ Computer
(128k or more memory), supports MyDOS up to 16MB and MyDOS subdirs...; still
written in Turbo-BASIC; many applications and drivers; freeware;
http://www.atarixle.de/

- XL-TOS a small and "cheap" GUI version from Atari magazin (i.e. a type-in
listing; the BASIC file, which consists of many data lines creates a short
object code file); unfortunately this GUI only looks good, it loads almost
nothing... PD;

- ST-TOS a small BASIC program, that looks like a GUI; it can merely load
BASIC files and do a few DOS commands, like lock, unlock, delete and such...
(PD)

- BASIC desktop, a GUI written in BASIC just as a sample, what can be done
with an 8-bit computer; this one loads BASIC and text files (maybe also ML
files); PD;

- DCS, the desktop construction set from Tom Hunt; there are 3 different
versions avaiable, a) for DOS 2.5, b) for MyDOS andc) for Sparta-DOS; I have
tested the Sparta DOS version, which worked with batchfiles and could easily
load some ML files, text files and BASIC files (which were already on the=
 DCS
disk); it also works with high densities and/or hard disk partitions up to
16MB and supports subdirs of course; hmm, freeware or shareware ?!?

- ATOS - GUI by Tom Hunt/Closer To Home.  http://cth.dtdns.net/atos/
  1) Lets you use any demo or intro as a screen saver!!
  2) Works with all Atari hardware, BB, MIO and Hard drives, SpartaDOS=
 support
  3) Lets you run files like full games and demos and then
     return back to the desktop.  It uses Overlays.

- Atari Desktop by ABC software (Poland), includes editors, converters,
file copiers, sector copy, tape+turbo tape copy, small games, CMC finder
and player and much much more; works with 64k RAM and keyboard input;
disk manuals only in polish language...

- Windows XL a Turbo-BASIC GUI with some nice add-ons, like calculator,=
 editor
and other things. written in 1986-1988 by Joerg Forg.

- there are a lot more GUI programs, however many of them are written in=
 BASIC
or Turbo BASIC and are very restricted; most of them merely look like a GUI
but need to much memory for everyday use. Thats why most users still prefer
those DOS or Gamedos (Gameloader, Multiloader, etc.) programs...

------------------------------

Subject: 7.8) What should I know about modem device handlers?

In order to use a modem on the Atari, a modem software handler, or R: device
handler, must be loaded into memory.

There are several families of R: handlers, corresponding to the different=
 ways
in which a modem may be attached to the Atari.

Except for family #7 below, these handlers are used in one of two ways.=20
Either they are (A) loaded into memory from DOS just before running the main
terminal application, or (B) the terminal program is appended to the=
 handler,
so that in practice, a single file is loaded from DOS which contains both=
 the
R: device handler and the application itself.

1) 835/1030/XM301 modems.  Atari-only modems, interface via SIO

2) MPP/Supra modems.  Atari-only modems, interface via joystick port

3) R-Verter cable. Connect standard Hayes-type modems via SIO
   / SX212 modem. A Hayes-compatible modem, interface via SIO

4) SWP ATR8000 interface. Standard Hayes-type RS232 modems via this=
 interface.

Richard Anderson writes (Oct 2 02):=20
  Mine originally came with a driver program; and, I believe, a BASIC=
 program
  to set up the driver from BASIC.  Later they shipped with a special=
 version
  of MyDOS with the R: handler built in.

5) 850 Interface/P:R: Connection, internal

This type of "mini handler" simply loads the R: device handler code from a=
 ROM
chip inside the RS232 serial interface.  A long beep is heard through the
speaker when the handler is loaded into the computer's RAM.

Many varieties of DOS for the Atari include an explicit provision for=
 loading
this type of R: handler into memory from the 850 or compatible interface.

Also, this type of R: handler is automatically loaded when any 8-bit Atari
computer is turned on with a P:R: Connection or powered 850 connected, but=
 no
powered disk drive is present.

6) 850 Interface/P:R: Connection, external

Used with the 850/P:R: Connection in place of these interfaces' built-in=20
handlers.

7) MIO/Black Box interfaces, internal=20

These interfaces utilitize the PBI or ECI parallel ports on the Atari.  They
include their own R: handlers in ROM, using no computer RAM at all.

8) MIO/Black Box interfaces, external: Len Spencer's Hyperspeed

This handler is "optional" for the Black Box, but "essential" for the MIO
in order to take full advantage of the high-speed hardware handshaking
capabilities of these two interfaces.

The goal is to give information about all available languages
for the Atari 8-bit computer. This information includes:
title, last version, author, date and a short description.
It would also be nice to know how to get it and where to get
more information (like reference cards, reviews and such).

        e) LISP
        f) FORTH
        g) PILOT
        h) LOGO
        i) All the rest

The following format is used:

Subject: 8.3) What games support 4 or more simultaneous players?

contributors to this section:
Jeff M Lodoen, Vidar \"Hawk\" Olavesen, Pat Mulvey,
Steven E. Posey (Party Quiz), Andreas Magenheimer

a) The following games support 3 simultaneous players:
   (2 players via joystick, 1 player via keyboard)

- Dynakillers by GMG/Slovakia (Freeware!)
- Blastermind by Numbercruncher/Germany (Freeware!)
- M.U.L.E. cracked+changed by CSS/Germany (pirate copy!)
- some more PD and commercial games...

b) The following games support 4-joystick head-to-head play:
   (Only the 400 and 800 computer models sport 4 controller ports)

- Asteroids cart. by Atari,
- Basketball cart. by Atari,
- Dandy disk by APX,
- M.U.L.E. disk by ECA,
- Maze War disk or cart. by ???,
- Silicon Warrior disk or tape by Epyx,
- Survivor disk or cart. by Synapse,

  (PD game written in Atari BASIC);
- Tank Battle by ??? from Antic magazine
- Roadblock by Brian Holness from Compute! magazine
- Battle Room (CIA vs. KGB) a PD game by SNACC
- Aliens a PD-game by ??? using an altered Dandy program
  (the Dandy font and thus the graphics were changed, however,
   the levels remain the same and can be used in both games);
- Sky Warrior by ??? from ROM magazine, June 1984 ***
- Depth Warrior by ??? from ROM magazine, Aug. 1984 ***
- Yellow-Brick-Road by ??? from ROM magazine, Feb. 1984 ***

*** these programs are reported to be 4-player programs, I'm
    not sure if they are meant to be 4-players simultaneously
    or 4-players - one after another (try to find out!);

c) The following games support 8 players on the 400/800 or 4 on the other
computer models, using the 2 controllers-per-port CX30 Paddle controllers:

- Super Breakout by Atari,
- Worms by Electronic Arts
  (has nothing to do with the PC game!)

d) The following game supports 4 players on all machines, using special
4-button keypad controllers linked together with RJ-11 jacks (standard
phone jacks) to a box with 2 joystick port connectors:

- Party Quiz by Suncom

e) The following programs support multi-joystick games, using extra
   hardware called Quadrotron (from the german Atari magazin 2/1989):=20
 =20
- test program for 4 joysticks (and assembler source);
- Quadro-Tron by H.Schoenfeld (4-player Tron-clone);

f) The following programs support multi-joystick games, using extra
   hardware called Multijoy (multijoy4 for up to 4 players, multijoy8=20
   for up to 8 players and multijoy16 for up to 16 players; originally
   developed by Raster/Radek Sterba, but also available from ABBUC):

- Cervi by R.Sterba (up to 8-players Snake-clone);
- Multijoy by R.Sterba (up to 4 players Tetris-clone)
- Bremspunkt by T.Butschke (up to 4 players Car-race);
- Sheep by F.Dingler (up to 8 players Sheep-race);
- Cards by F.Dingler (up to 8 players grab-a-card-game);
- Ice-Hockey by F.Dingler (up to 8 players Icehockey-game);
- Quadrotron-M4 by R.Sterba (patched Quadro-Tron for Multijoy);
- Shoot Em' All by R.Sterba (16 players shooting-game)

Andreas Magenheimer adds:
To get an overview or see a chart of OS changes from the 800 to the XL
line, refer to Antic magazine Volume 3, Number 2 (June 1984), pages 10-14;
Also note, that some software will not work correct (or not at all) on
newer XE/XEGS versions (which have a new OS with a new version number,=20
a new selfttest/memory-test/keyboard-test, larger RAM chips, etc. etc.);

Subject: 8.10) What kinds of RAMdisks can be set up on the Atari?

This section by Andreas Magenheimer.

 8.10 Atari Ramdisks - An (incomplete) Overview:=20
      [This is version 2.8 from July 2003]=20
=20
Right from the start of the Atari 8-bit computer era in the late 70`s, =20
Atari users wanted to have as much RAM as possible (or as their purse =20
could afford). Having a 16k machine with a tape device was nice and =20
cheap, but having full 48k or 64k and a floppy drive was much nicer =20
(and very expensive). Thus many Atari users began to create selfmade=20
RAM extensions and enhancements, just to save some money. Also a lot of=20
firms provided extra RAM, RAM enhancements, RAM extensions and Ramdisks.=20
Besides Atari there were (and still are) quite a lot of producers,=20
manufacturers, distributors and authors of such RAM enhancements... =20
=20
This "short" and incomplete overview does not provide any docs or manuals, =
=20
but gives some info about the various Ramdisks on the market. Since these =
=20
notes are written by me, they will merely contain the information I have.=20
And as you all can see - it isn`t much information. So any help and extra=20
info, as well as corrections, are very welcome. It would be nice to see=20
this text & info growing. For now let us start here, the info-section is =20
divided into 8 groups: =20
=20
1) Name (Name of the RD, e.g. Megaram 2 or Rambo XL or MIO, etc.);=20
2) Vendor/Author (or distributor, manufacturer, producer, etc.);=20
3) Size (size of the Ramdisk only; NOT the full computer memory);=20
4) [Bankswitching] Area (for XL/XE computers usually 4000-7FFF);=20
5) Banks (hexadecimal input count, as in MyDOS or RAMDTEST.BIN);=20
6) Control Bits (which bits are used to control the Rambanks);=20
7) Port (control Port - usually Port B for XL/XE machines);=20
8) Notes (any extra info, comments, miscelleanous things, etc.);=20
=20
If you wish to add any other type of info, let me know. The above=20
information should be enough for most programmers to support a RD in=20
their programs (especially to support more than just one type of RD).=20
Hopefully future programs will take care about this info or just use=20
a small setup program to setup any kind of RD. Now let me begin:=20

Subject: 8.11) What programs support a RAMdisk?

This section by Andreas Magenheimer.
=20
       8.11 Ramdisk-supporting Software:
    (This is Version 2.8 from July 2003)


Well, I will only list those programs here that have BUILT-IN! ramdisk=20
support. Why? Simply, because most if not all PD programs can support=20
a RD, as soon as the user a) has a certain DOS or RD driver or b) has=20
a special OS inside the computer or c) has any kind of special and=20
non-standard hardware. Just one example: With the use of QMEG+ OS it=20
is possible to freeze ZORK (or any other protected / unprotected program)=20
into the RD, then re-direct the RD as being drive 1 and finally boot=20
Zork off of the Ramdisk, allthough Zork does not support a RD in any way.=20
The same funny things can be done to other copy protected programs and=20
especially to unprotected public domain programs... Now, let me begin:

Subject: 8.13) What voice/sound synthesis software is there for the Atari?

This section by Andreas Magenheimer.

- S.A.M. - the Software Automated Mouth by Don't Ask Software (a=20
  software package; you can find it at Don`s / the author's homepage:
  http://www.retrobits.net)
- Softsynth (a PD program, that creates sounds and sound effects via
  modulation of the tv/monitor speaker; available from the ABBUC library);
- MOD-Sounds (sound-MODulation, allthough I do not know any software to
  create such sounds on an A8, some programs to edit (Protracker) and
  playback (Inertia, Modplayer, Neotracker, etc.) these sounds do exist);

------------------------------

Subject: 8.14) What programs support stereo and upgraded sound?

This section by Andreas Magenheimer.

There is already a lot of stereo software for the upgraded Atari computers
available, of course most of these programs are limited to certain/special
upgrades and merely perform their stereo effects on these items (with
otherwise upgraded or non-upgraded Ataris, the sounds or programs will
only play in mono):

a) software for the various stereo-upgrades:

- stereo with one Pokey (POPS-software): Afaik for this kind of upgrade,
  there merely exists a patched version of the Pokey player program, I am
  not sure if there is anything else for it; anyway, refer to Analog=20
  Computing, issue 66, november 1988, pages 54 -60;

- stereo with two computers (thus two Pokeys): Afaik for this simple trick
  there merely exist two programs, they are "Perestroyka" and "Sky=20
  Network" by T.Liebich. In order to achieve the stereo effect, you
  have to boot/load one of these demos on two computers (connected to
  different TV's or monitors, there is no need to connect the computers to=
=20
  each other!). When done, press 1-5 on the first computer while pressing
  Shift-1-5 on the second computer. Meaning, if you want to hear the first=
=20
  sound in stereo then press 1 on computer 1 and press Shift-1 on=20
  computer 2 simultanously (that`s a little tricky, I know). If you want
  to hear sound 5 in stereo, then press 5 on computer 1 and Shift-5 on
  computer 2 simultanously. Tricky at first, but sooner or later you will
  get the hang of it. Of course you can also connect the two Ataris to
  a hifi-system, using the sound output of one Atari for the left channel
  and the sound output of the other Atari for the right channel...

- stereo-sound with Stereo-Blaster Pro (Portronic/AMC): Afaik there was
  at least one demo disk (early version was single-sided only, later=20
  versions were double-sided), that contained some demo-software, namely
  the simple "Stereo-demos" (by AMC, side 1) and the "Stereoblaster-Demo"
  (by HU-Soft, side 2 if available). The Stereoblaster demo was written=20
  in Turbo-Basic and played back via Compiled-Turbo-Basic, it uses Chaos
  Music-Composer Sounds (*.CMC) and a few of these provide stereo effects,
  if equipped with a stereo-blaster-pro and a hifi-system. The simple=20
  stereo-demos included some programs written in Atari Basic, for example
  a (pong-like) bouncing ball and a flying helicopter. Equipped with a
  stereo-blaster-pro and a hifi-system, one could see the ball bouncing
  left and right and simultanously hear the sound fx on the left or right
  channel. The helicopter started at the left side and produced a loud=20
  sound on the left channel, when it was flying to the right side, the=20
  sound faded on the left channel and got louder on the right channel,=20
  until the helicopter disappeared (and the sound completely faded away).=20
  There were some more of these simple demos available, but I don`t=20
  remember them anymore.

- Stereo with two Pokeys: There already exist dozens of sounds and demos,
  that support this upgrade, most of these programs were made in Poland,
  but a few sound-demos were also made in other countries. Anyway, the
  following programs support stereo via two Pokey chips:

  - Alf-Demo by the Unknown Base (Netherlands);
  - Alpha-Demo by GMG (Slovakia);
  - AMS-Stereo player by ??? (author unknown), USA;
    (there are at least two AMS-stereo-players, that let you play
     *.AMS sounds in true stereo or at least simulated stereo!);
  - ARS-Mori 16k Intro by Tristesse (music shortened and ripped from
    Drunk Chessboard by Infinity!), Poland of course;
  - Ballada sound by DJ V / BK (Poland);
  - Base 33 by AIDS (msx by Greg, Poland);
  - Chaos Music Composer version x.x patched by ??? , Poland;
    (=3D> the original version by Janusz Pelc / LK Avalon is only mono,
     but there is a patch available, as well as various patched CMC
     versions on the internet; thus *.CMC sounds can be generated in
     stereo!);

    Chaos Music Composer;
  - Cogito-Demo by AIDS (Poland)=20
  - Do you see the light? sound-demo by Roemer of UNO (Germany); =20

  - Drunk Chessboard by Infinity (music by X-Ray!), Poland;
  - Dynakillers (Game) by GMG, Slovakia;
  - First of All (sound) by Raster, Czech Republic;
  - Impossible but Real Demo by MacGyver (Poland);
  - King of Aggregat by X-Ray / Slight (Poland);=20
  - Megaplayer Versions 1.6 and 2.0 by MacGyver (Poland)
    (=3D> and thus all *.CMC, *.MPT, *.TMC, etc. sounds played with
     this sound-player tool can be heard in true or simulated stereo!);
  - Multi-Pro-Tracker 2.4 (various versions) by Jaskier/Taquart?
    (=3D> thus *.MPT sounds can be generated in stereo!), Poland;
  - (many) *.MPT sounds created by the stereo-version of Multi Protracker;
  - Nazebany by DJ V / BK (Poland);=20
  - Overload sound by X-Ray / Slight (Poland);
  - Raster Music Tracker 1.x by Raster, Radek Sterba (a PC program=20
    that creates mono/4-channels or stereo/8-channels *.RMT sounds that=20
    can be played back on the A8 or any Atari 800/XL/XE emulator);
  - (most) *.RMT sounds created by Raster Music Tracker;
  - Stereo-Patch for Pokey Player by ??? (author unknown)
    (=3D> thus all Pokey-Player / *.V sounds can be heard in stereo!);
  - Stereo-Patch for Softsynth by Freddy Offenga (Netherlands)
    (=3D> thus Softsynth will create stereo-sounds!);
  - Stereo Patch for World of Wonders by Freddy Offenga (Netherlands)
    (World of Wonders is a great Softsynth sound-demo!);
  - Still Alive (TMC-sound) by Greg, Poland;
  - Time sound by X-Ray / Slight (Poland);
  - Theta-Music-Composer version 1.x by Greg (Poland)
    (=3D> thus *.TMC sounds can be generated in stereo!);
  - (most) *.TMC sounds created by Theta Music Composer;
  - Vanity sound by Kuchara / Excellent (Poland) ;
  - Worms (320k-Demo) by Datri, Czech Republic;
  - Zybex, patched version by ANG and/or Micro Discount (NL/UK)
    (the original version by Zeppelin games is only mono!);
  - thats all what I found so far... (A.M.)

b) software for other sound enhancements:

- enhanced-sound with Covox: Afaik this upgrade will playback digitised or
  sampled sound in 8Bit resolution rather than in 4Bit resolution. The=20
  following programs support the Covox-Upgrade:
  - Inertia 2.9, a MOD-player by MadTeam;
  - Inertia 4.5, a MOD player by MadTeam;
  - Protracker x.x, a MOD-editor and player by ???;
  - NeoTracker 1.x, a MOD+NEO+... player by EPI/Allegresse;
  - that's all I have found so far;=20
note that all programs (except neo-tracker?) will still work with pokey...;

Subject: 8.15) What games support online action via modem?

This section by Andreas Magenheimer.

- Modem Chess, a PD game in Basic by ???
- Modem-Battleships, a PD game in Basic by ???
- Tele-Chess, a PD game in Basic by ???
- probably some more games...

(I have also seen an advert from GCP in Analog or Antic, that listed
 the following games: The City, Cybertank, Cybership, Bio-War, Lords
 of Space; I am not sure if they are all available for the Atari, A.M.)

To play these games online, one would not only require an Atari computer,
but also a modem, a modem-driver and/or a terminal program (like Kermit,
Bobterm, Teleterm, A-Term, Ice-T, BBS Express Pro, etc.). See also the
sections 7.8, 10.1 and 10.2 which tell you more about modem/terminal
programs and modem hardware for the Atari...

Subject: 8.16) What programs support Atari computer networking?

This section by Andreas Magenheimer.

There are two different hardware add-ons which provide a "computer-=20
network" (two or more Ataris linked together). Thus, there is software=20
that supports either one or the other hardware (namely Gamelink-1 or
Gamelink-2). The following software supports the networking hardware:

- Gamelink-1 (by Dataque):=20
  - info-text about GL-1 and where to buy it, by Dataque;
  - Tic-Tac-Two by J.Potter/Dataque, a tic-tac-toe clone;=20
  - Modem-Battleships, patched by Rick Detlefsen for Gamelink-1;

- Gamelink-2 / Multilink (by Dataque & Bewesoft):
  - info-text about GL-2 and where to buy it, by Dataque;
  - info text about Maze of Agdagon demo, by Dataque;
  - Maze of Agdagon demo (1 player only) by Dataque;
  - documentation for Maze of Agdagon (full version) by Dataque;
  - Maze of Agdagon (full version, 2-8 players) by Dataque;
  - description of multilink/gamelink-2 hardware and schematics by
    Bewesoft (two texts, one in czech and one in english; schematics
    presented as an Atari Gr.8 picture for a) easy-2-computer hardware
    and b) more complicated 2-8 computer hardware);
  - Multi-Dash (2-8 players, XL/XE only) by Bewesoft;
  - Multi-Race (2-16 players, XL/XE only) by Bewesoft;
  - description of "how to program networking games for multilink
    [gamelink-2] hardware" (text available in english and czech, with
    lots of source codes and OS adresses/variables/...) by Bewesoft;
  - Multi-Worms (2-8 or 2-16? players, XL/XE only) by Bewesoft;
  - complete + documented source code for Multi-Worms by Bewesoft;
  - "starter-kit" module to use in your own networking-games by Bewesoft
    (free use of this module is granted by Bewesoft/Jiri Bernasek);

Subject: 9.1) How can I work with .arc files on my 8-bit Atari?

ARC.EXE for MS-DOS was released by System Enhancement Associates (SEA)=
 around
1985.  It will compress and store groups of files as one file, making it
easier and quicker to download programs and support files at once.  Because=
 of
the ease of use and availability of this program, it quickly became the
defacto standard for file archives on Intel-based IBM machines.  Files
compressed and stored with ARC or a compatible utility are normally given=
 the
filename extender ".arc".

The 8-bit Atari computers have several software utility options that are=
 fully
compatible with ARC.EXE, the most important being:

Super UnArc 2.4 and Super Arc 2.4 - shareware by Bob Puff, released 01/31/89=
=20
Available:=20
http://www.nleaudio.com/css/files/superarc.arc (complete package + docs)

Also, SpartaDOS X includes a fully compatible ARC command for both creating
and extracting .arc files.

------------------------------

Subject: 9.2) What file formats for entire disks/tapes/cartridges are there?

It is now common, especially when working on Windows PCs or Macs, to work=
 with
Atari software as files or "images" containing the data from an entire disk,
data cassette, or cartridge as duplicated from the native media for the=
 Atari.

Here is a list of file formats, arranged by their associated filename
extensions.  These are all filename extensions used to name files containing
entire 8-bit Atari floppy disk images, cassette tape images, or cartridge
images.

.DCM -Image format invented by Bob Puff, for his Disk Communicator 3.2
utility.
      Used when working with native Atari hardware.
      DISKCOMM is at http://www.nleaudio.com/css/files/DISKCOM.ARC
      DCM specs at: http://home.planet.nl/~ernest/diskcomm.zip

.ATR -Image format invented by Nick Kennedy, for his SIO2PC project.
      Used with most 8-bit Atari emulators running on other computer
      platforms.  SIO2PC is at http://www.tcainternet.com/wa5bdu/

.XFD -Image format invented by Emulators Inc, for their ST Xformer emulator.
      Identical to ATR except without the 16 byte header.
      Used with ST Xformer and PC Xformer emulators.
      Xformer is at http://www.emulators.com/
     =20
.PRO -Image format invented by Steven Tucker, for his APE ProSystem device.
      Used with APE, the Atari Peripheral Emulator.
      APE and APE ProSystem are at http://www.atarimax.com/

.SCP -SpartaDOS SCOPY image file. SCOPY was a utility by ICD.

.DI  -Image format invented by Kolja Koischwitz & Christian Kruger for their
      800XL DJ emulator for the Atari ST.

.CAS -Cassette image format invented by Ernest R. Schreurs, for his=20
      Digital Cassette Image system (includes CAS2SIO, WAV2CAS, and CAS2WAV
      MS-DOS utilities.  See: http://home.planet.nl/~ernest/

Subject: 9.3) How can I copy my copy-protected Atari software?

Russ Gilbert writes:

Almost all commercial software for the A8 is/was copy
protected. For boot disks, this usually involved a large
number of special formatting that couldn't be copied using
ordinary sector copiers. Usually the boot process involved
checking to see if a certain sector error occurred, then
proceeding. If the error did not occur, the disk was a copy
and would not work.

For carts, usually the method of protection was to write to
the cart area of memory and see if the value changed. If the
value changed, the cart program was in RAM, not ROM and
would fail to operate.

For tapes, again a fair number of schemes were used. Some
varied the speed at which the tape loaded. I'm not familiar
with tape protection schemes.

With all software media (cart, tape, disk), there may be
program encryption, which must be decrypted before the
program can run. This to make more difficult disassembly of
the program.

There were/are a number of products to defeat copy
protection/allow copying of protected software for the A8.
The most common way to defeat copy protection was to
disassemble the software and revise sections of code so that
the copy protection was defeated. A software with defeated
copy protection is called a 'cracked' software. The basic
procedure is to understand how cart/tape/disk software
initializes, loads and runs. Usually make a file out of the
software and 'follow the code', starting with loading of
the program, to decryption to the actual running of the
program.  Today, it is unnecessary to copy original
commercial A8 software because it has already been defeated
and may be found at a few ftp sites. (Note umich archive has
no commercial/non-shareware software.)

Besides 'cracking' software, there were/are hardware devices
to copy commercial protected software. The Happy 1050 and
the Archiver, and probably other modifications to the 810,
or 1050 allowed 'bit image' copying and reproduction of the
special formatting that copy protected disks had. Using
these archiving disk drives, a copy of the original disk,
including all special formatting and the original code is
copied, thus making a copy protected copy, not cracked, just
like the original.

For carts, copying could involve cracking or again there
were/are products to reproduce the cart and simulate a ROM.
Or the cart might be copied and burned on the correct type
of eprom, to make a plug in cart. 'The Impersonator', the
'Pill' are two cart copy schemes copy the cart to a file,
then don't change the code, but use a 'dummy cart' to fool
the software into thinking there is a ROM present.

Basic tools for copying, then cracking, carts and disks are
a sector editor and disassembler. Carts are usually most
easily dumped using a special OS, like Omnimon, to interrupt
the cart and dump memory to disk. There are a few pd cart
copiers that have the user plug the cart in when the program
is running, I don't believe these pd cart copiers are very
good or very wise to use.

So, the basic answer to 'how do I make a copy of my copy
protected commercial software' is don't bother. Find it on
the net.

There is one exception, in that this 'solution' involves a
minimum of effort and is relatively safe. I refer to
'Chipmunk' and 'Black Patch' software to make cracked boot
disk copy of commercial disks. HOWEVER, even if you use
these two commercial archival tools, be sure you write
protect your originals, and be careful not to accidentally
write to the original disk.

Finally, I'll mention a very modern (I mean 1997) product.
The APE ProSystem, by Steven Tucker, in the registered
version of this shareware allows making disk images called
'Pro' images. APE (Atari Peripheral Emulator) requires a
cable, called the SIO2PC cable, that connects the A8 13 pin
serial port to a serial port on the IBM PC clone. To make
'Pro' images, a special adapter cable is needed, not just
the 'standard' SIO2PC cable. The 'Pro' image can 'capture'
the copy protection of an original commercial disk. The
'Pro' image can then be loaded into an A8 using the APE
registered version software, thus backing up your original
disk software. Note the 'Pro' image will only be of use to
person(s) owning registered APE software and 'Pro' adapter
cable.

Subject: 10.2) What programs can I use to host a BBS on the Atari?

The 8-bit Atari was particularly popular for hosting a dial-up Bulletin=
 Board
System (BBS).  Uploading/downloading files, online messaging, even online
gaming services can all be hosted on an 8-bit Atari operated as a dial-up
BBS.

This section attempts to list all BBS programs for the Atari.  Of these, BBS
Express! Professional and Carina BBS seem to be programs that stand up well
even today.

Contributors to this section include: Winston Smith, Steven Sturza, Chad
Hendrickson, Don Fanning, Matt Singer, Pete Davis, Jeff Williams

  o  AMIS BBS --  The Atari Message Information Service, public domain.
The "granddaddy" of BBS programs for the 8-bit Atari.

The AMIS BBS was written in BASIC by people from the Michigan Atari Computer
Enthusiasts.  It included designs for a ring-detector.  You needed a sector
editor and had to allocate message space by hand, hex byte by hex byte.

Several versions of AMIS:
     *  Standard AMIS
     *  MACE AMIS - from the Michigan Atari Computer Enthusiasts
     *  Fast AMIS
     *  MPP AMIS by Matt Pritchard
     *  TODAMIS 1.0, for 1030/XM301, 1986, Trent Dudley

  o  ATABBS -- Rod Roark writes (3/12/03):
    This is really straining my memory -- don't recall exactly
    when I wrote the thing (maybe '80 or '81), but as far as I
    know ATABBS was the world's first BBS for the Atari 400/800.
  =09
    I ran it out of my condo in Atlanta on a 48K 400 with an 80K
    floppy drive and a 300 bps Hayes Smartmodem.  The 48K memory
    module was a third party add-on, not Atari's.
  =09
    It was written in Atari BASIC with a few bytes of machine
    language thrown in.
 =20
  o  ATKeep --  An Atari 8-bit version of CITADEL BBS, by Brent Barrett
ATKeep is a Citadel-like BBS system for eight-bit Ataris.  ATKeep runs under
SpartaDOS and requires BASIC XE and 128K of RAM.  Originally "MBBBS (Message
Base Bulletin Board System) 1.0, March 24th, 1986" MBBBS was changed to=
 Atari
Keep, or, ATKeep for short, around version the time version 4.0 was released
(June 15, 1986).

ATKeep 7.0 finally took the aide and cosysop commands out of a menu section
and put them into extended commands, where they belonged.  It also added a
SYSOP level command set.  Users were no longer "users" "aides" or=
 "cosysops,"
they had become level "A" (SYSOP) through level "Z" (READ ONLY).  The system
had become extremely complex. Public, hidden OR password protected PRIVATE
rooms.  Each room now had its own access level (thus keeping people of lower
level from getting in EVEN if they knew the room name).  Each room was
assigned a RWRT (or Read WRiTe status), which determined who could enter
messages in it, and whether or not public or private messages, or both were=
 to
be allowed.

Before version 7.0, ATKeep only worked with the Atari 1030 or XM301 modems.
ATKeep 7.0 was rewritten to accomodate the 850 or PRC interface allowing use
of any Hayes compatible modem.

ATKeep version 7.50 was released (1987), was version 8 released?

  o  BBCS -- Bulletin Board Construction Set, by Scott Brause/Antic, 1985
A machine language program, developed as the Jersey Atari Computer Group
(JACG) BBS system.

BBCS was known for it's great flexibility.  The sysop was offered easy
customization by the use of menus.  Many BBSes before it required that you=
 had
to actually change the BASIC code in order to customize your BBS.

Unfortunately, it also suffered from a reputation for stability problems.

  o  BBS Express!  -- 1986, Leith Ledbetter/Orion Micro Systems
Written in compiled Action!.  1030/XM301 and 850 versions.

  o  BBS Express! Professional ("PRO") --
Originally by Keith Ledbetter/Orion Micro Systems, now still a commercial
product of Video 61, http://www.atarisales.com    =20
See also http://cth.dtdns.net/pro/pro1.html

Written in 100% machine language.

Requires XL/XE, SpartaDOS 3.2+, hard drive highly recommended, or at least a
large ramdisk.  R-Time 8 is fully supported.

  o  Carina BBS -- a shareware product of Shadow Software/David Hunt.
Carina II was originally developed by Jerry Horanoff/CARINA Software Systems

Requires an XL or XE computer, at least 500K of storage capacity (including
ramdisk and drives), and SpartaDOS version 2.3 or greater.
Recommended: 192K ramdisk or greater, and an R-Time cartridge.
Fully supported: An MIO interface and a hard drive.

Pete Davis writes (15 Aug 2002):
Carina was a pretty powerful BBS system.  Though it was written in BASIC=
 (with
a number of machine language routines), it was expandable and had was able=
 to
load new BASIC programs with the BBS running.  In fact, it was quite modular
and would load different sections of the BBS at runtime.  I actually used it
when I ran a BBS some time back.

Carina 2.6 is available at:
http://www.umich.edu/~archive/atari/8bit/Telecomm/Bbs/carbbs26.arc

Carina is also at:
http://www.aracnet.com/~atari/ftp/car_bbs.arc (download doesn't work for me)

  o  Carnival BBS -- essentially AMIS with an overlay to allow for private
                     messages and passwords.

  o  FoReM BBS --  Friends of Rickey Moose BBS.  By Matt Singer.
At the time, there were a lot of BBSs around called things such as=
 "FORUM-80"
and "BULLET-80", ergo the name.  FoReM BBS was the first truly RBBS-like BBS
for the ATARI 8-bit.  It was programmed in BASIC and was somewhat crashy.  I
think that this is the great-grandparent of the FOREM-XE BBSs that survive
today.

Matt Singer writes:
FoReM BBS derived from an early AMIS. When multiple message areas were
added the name was extended to FoReM 26M.  Then, When OSS released BASIC
XL the program was rehacked and called FoReM XL... Bill Dorsey wrote most
of the Assembler routines (where is he now?).

  o  FoReM XL BBS -- by Matt Singer.
FoReM BBS updated to take advantage of BASIC XL from OSS.

  o  FoReM XE BBS -- by Matt Singer
This version of FOREM BBS requires the commercial BASIC XE cartridge in=
 order
to run.  It is in the public domain and can import and export messages from
the Atari PRO! BBS EXPRESS-NET (7-bit text only, control ATASCII graphics=
 are
reserved for message data-structure bytes).=20

  o  FoReM XE Professional BBS / FoReM XEP BBS -- by Len Spencer
A re-write of FoReM XE BBS, last version was 5.4, Jan 5 1993.
FXEP requires an XL/XE computer with at least 128k of memory, the BASIC XE
cartridge from OSS/ICD, SpartaDOS 3.2 (this program will NOT work with any
other version), and at least 500K of storage.

FXEP is in the public domain, http://members.aol.com/lenspencer/

  o  NITE-LITE BBS --  Paul Swanson's BBS with RAM disk.
Paul Swanson was a programmer from the Boston, Massachusetts, USA, area.

"1983: Nite-Lite B.B.S. goes on the air. (Was it running A.M.I.S. ?) It is
called "Nite-Lite" because the computer monitor casts an eerie glow about=
 the
room.  1984: Paul Swanson writes his own BBS hosting software for the ATARI
6502 8-bit computer.  He names it "Nite-Lite".  The Nite-Lite BBS hosting
software goes on to be the most successful commercial BBS software ever
written for the ATARI 6502 8-bit computer.  1989: Nite-Lite BBS puts in a
second line. (MichTron boards eventually take the place of all of the ATARI
Nite-Lite boards.)" - Winston Smith

This BBS was the first to support a RAMdisk, which Paul Swanson called a=
 "V:"
device for "virtual disk".  This BBS was written in Atari BASIC and required=
 a
joystick hardware "dongle" device.  This was notable as being one of the=
 first
Atari 8-BIT BBSs that could actually go for a week without having to be
rebooted.  Pointers to the message base were kept in an Atari "very long
string" (for which Atari BASIC is famous).  The BBS would only have problems
(for the most part) if this string became corrupted.

  o  OASIS (the commercial version) / OASIS Jr. (the pd version)
Originally by Ralph Walden, then Leo Newman took it over, followed by
Glenda Stocks/Z INNOVATORS, then Alf (Jeff Williams).
=20
All machine language.  OASIS is very crash-resistant and comes with a "dial
out" screen so that the Sysop can use the BBS as a terminal program to call
and fetch files without having to bring the BBS down and reload a terminal
program.  OASIS supports "Door programs" which it refers to as "OASIS PAL
modules".  An excellent message system, and a complex file system.  It
consists of "file libraries" with suites of "file types".  There is quite a
bit of overhead involved in performing a download (which may be a good=
 thing,
as it discourages file hogs).  OASIS IV performs networking.

Glenda Stocks writes at http://world.std.com/~snet/glenda.htm :
I purchased the source code rights to OASIS and began marketing the BBS
software to Atari 8-bit enthusiasts around the world.  I felt that I had the
superior BBS software because I had programmed in the ability to run=
 external
programs, including online games and user surveys.  I also had added color
prompts for IBM clone users who called Atari boards running my OASIS=
 software.
Sometime in 1991...I sold the rights to OASIS to a man in Canada..

Jeff Williams ("Alf") writes: (12/6/02)
OASIS was around prior to either PRO or BBS Express IIRC. I don't know when
exactly it showed up, version 3.09 was the first one I remember seeing. What
made it nifty was it was very fast, being all assembler, and having some
different features that things like Forem & Carina didn't have. Compared to
something like Forem MPP at the time, it was kind of amazing.

Ralph Walden sold it to Glenda Stocks, who chopped it up into modules and=
 sold
it as ver 4.7.  PRO was out by then, and was a much more complete offering
imo.
Glenda wrote some modules for 4.7, but it never really went anywhere because
the architecture was so cramped with her changes.

Eventually she gave up and sold me the source. I looked it over and realized
it was a mess and nothing was going to happen with it. I worked on a version=
 5
for a while, but never made much progress.

  o  SMART BBS --  by Marco Benton.
This program is written entirely in BASIC.  It expects to be running under a
SpartaDOS environment.  This BBS program uses a "modem clock string" rather
than an R-Time 8 cartridge in order to retrieve the current time.  It also
comes with an Atari BASIC game door called "Sabotage".

Subject: 10.3) How can I read/write 8-bit Atari disks on an MS-DOS PC?

There are several programs that allow an MS-DOS system to work with an
Atari-format 5.25" diskette.  Each of these work with the Atari SS/DD 180K
format, so you'll need an Atari DOS and disk drive capable of this format.=

MyUTIL by Mark K Vallevand.  Based on Charles Marslett's UTIL.
  http://www.umich.edu/~archive/atari/8bit/Diskutils/Transfer/myutil.zip
  Includes SpartaDOS disk utility v0.1e to access 180K SpartaDOS disks

Other similar utilities:

UTIL by Charles Marslett - Reads/Writes SS/DD 180K Atari disks.
  http://www.wordmark.org/

Here's some advice on using the above utilities from Hans Breitenlohner:

There are two technical obstacles to interchanging disks between
DD Atari drives and PC drives.

1. The Atari drive spins slightly slower (288 rpm instead of 300 rpm).
   If you format a disk on the Atari, then write sectors on the PC, it is
   possible that the header of the next physical sector will be overwritten,
   making that sector unreadable.  (The next physical sector is usually
   the current logical sector+2).  The solution to this is to format all
   disks on the PC.
       (Aside:  Does anybody know how this problem is handled on the
        XF551?  Is it also slowed down?)
     Konrad Kokoszkiewicz answers:
     "The XF551 disk drive is not slowed down - these drives are spinning
     300 rotations per minute. To prevent troubles with read/write disks
     formatted and written on normal Atari drives (288 rot/min), the main
     crystal frequency for the floppy disk controller is 8.333 MHz
     (not 8 MHz, as in 1050, for example)."

2. If the PC drive is a 1.2M drive there is the additional problem of the
   track width.
   The following is generally true in the PC world:
    - disks written on 360k drives can be read on either drive
    - blank disk formatted and written on 1.2M drives can be read on
      either kind
    - disks written on a 360k drive, and overwritten on a 1.2M drive,
      can be read reliably only on a 1.2M drive.
    - disks previously formatted on a 360k drive, or formatted as 1.2MB,
      and then reformatted on a 1.2M drive to 360k, can be read reliably
      only on a 1.2M drive.
    (all this assumes you are using DD media, not HD).

   Solution: Use a 360k drive if you can.  If not, format disks on the
   Atari for Atari to PC transfers, format truly blank disks on the PC
   for PC to Atari transfers.

Jon D. Melbo sums it up this way:
   So a basic rule of thumb when sharing 360KB floppies among 360KB &
   1.2MB drives is: Never do any writes with a 1.2MB drive to a disk that
   has been previously written to in a 360KB drive....UNLESS... you only
   plan on ever using that disk in the 1.2Mb drive from then on out. Of
   course a disk can be reformated in a particular drive any time for use
   in that drive.   As long as you follow that rule, you can utilize the
   backwards compatible 360KB modes that most 1.2MB drives offer.

While the above mentioned utilities work with SS/DD 180K Atari-format disks=
 or
SS/DD 180K SpartaDOS disks, the following combination of utilities has been
used successfully to read SS/SD 90K Atari-format disks.  So if you only have
standard Atari 810 and/or Atari 1050 drives, you could look into:

AnaDisk -- now a product of New Technoligies Inc. (NTI)

See http://ch.twi.tudelft.nl/~sidney/atari/ for tips on using this
combination of utilities.

Preston Crow writes:
  "As best as I can figure it out, if your PC drive happens to read
  FM disks (I'm not sure what the criteria for that is), then you
  can read single density disks on your PC by dumping the contents
  to a file with AnaDisk, and then using Deana.com to convert the
  dump file into a usable format.

  For enhanced density disks, Anadisk generally only reads the first
  portion of each sector, but it demonstrates that it is possible for
  a PC drive to read enhanced density disks."

    computers.  The RS 232 ports need to be connected
    together using a 'null modem cable'.
=20
    For up to 4800 baud, no flow control lines need be
    connected.  Just cross the transmit and receive lines
    and join the grounds together.  Transmit is pin #2,
    receive is pin #3 and ground is pin #7 on the 25 pin
    port. 25 pin #2 goes to Atari #4 (XMT to RCV), 25 pin
    #3 goes to #3 on Atari (RCV to XMT) and #5 of 850 goes
    to #7 of 25 pin (GND to GND).
=20
    The right hand pin on the 'long' side of a female 'D'
    connector is #1.  There are 13 holes on this 'long'
    side, 12 holes on the 'short' side.  The numbers go
    to the left 1 to 13 then #14 is under #1 and left again
    so that #25 is under #13.
=20
    Most term programs allow a null connection, without a
    carrier detect.  Notably, '850 Express!' does not. I have
    only used 'Procomm 2.4.3' (the last shareware version of
    Procomm) on the PC and BobTerm on the Atari, but other
    term programs may work.
=20
    To check your null modem connection, start both PC and
    Atari term programs, set baud to 2400 or 4800 on both
    computers. No parity, 8 data bits, 1 stop bit on the PC.
    Be sure to use the correct COM port on the PC.  Go to
    'terminal' mode and you should now be able to type on
    either computer and see it on the other screen. To
    accomplish a file transfer, use Y-modem probably from
    BobTerm, rather than X-modem. X-modem will often append
    bytes to a file transfer, an undesirable event. There is
    also a very nice Z-modem recieve program for the Atari,
    called ATAR-Z-MODEM by Larry Black for the Atari.
=20
    A convenient way to make a null modem cable, up to about
    30 feet long, is to use two female DB25 connectors
    (Radio Shack) some three or more conductor cable. Using
    the two DB25 female connectors allows unplugging your
    modems and plugging in the null modem cable into the two
    modem cables.  This also avoids the confusion of
    variations in the computer ports. Most computers connect
    into the modem end via a standard RS232 DB25 connection.
    With this both ends 25 pin cable, you would cross pins 2
    and 3 and connect the #7s together to make a null modem
    cable.
=20
    The SIO port on the Atari cannot be used directly. An
    850, P:R: Connection, MIO, Black Box or similar device
    that provides an RS232 port must be used.
=20
=20
    Following are pin assignments for a DB25 pin RS 232 C
    port.
1.  Protective Ground        12.  Select Alternate Rate
2.  Transmit Data            15.  Transmit Clock (sync)
3.  Receive Data             17.  Receive clock (sync)
4.  RTS (Request to Send)    20.  Data Terminal Ready
5.  CTS (Clear to Send)      22.  Ring indicator
6.  Data Set Ready           23.  Select Alternate Rate
7.  Signal Ground            24.  Transmit Clock
8.  Carrier Detect
=20
   For higher speed connections, above 4800 or 9600, you
   need the flow control lines and Atari term software that
   has flow control built in. You also need an MIO or Black
   Box, which uses the PBI (parallel bus). A high speed
   cable would need not only XMT, RCV, and GND, but also
   flow control lines.  I suggest a commercial null modem
   from computer store to ensure correct lines.  A null
   modem is a small adapter with the correct lines already
   crossed. I don't know how to correctly connect the CTS,
   RTS, DTR, DSR, CRX lines for a high speed null modem.
   With a null modem, you just plug it into the 25 pin
   connectors of the two modem cables you might already
   have connected to your Atari and PC or Mac. You may need
   a straight thru 25 pin gender changer also.
=20
   Following is in this FAQ elsewhere, but I summarize here:
   (Figure out or look for pin numbers on the ports.) Note
   that these are pin assignments, and NOT null modem
   connections with the XMT, RCV crossed and GND straight
   thru.

Note: * above indicates the difference between an AT 9 pin
and a Atari 8-bit 9 pin cable connector. eg. If you check
continuity from pin 3 of 25 pin end and it goes to pin
4 of nine pin end, you have an Atari serial cable. If pin
3 of 25 pin goes to pin 2 of 9 pin end, you have a PC
serial cable.

SIO2PC
=3D=3D=3D=3D=3D=3D
=46rom the SIO2PC home page, written by Nick Kennedy:

SIO2PC is a hardware & software package interfacing the 8-bit Atari to PC
compatible computers.

The original idea was to have the PC emulate Atari disk drives so Atari
programs could be stored on the PC's hard (or floppy) drives. It turned out=
 to
be quite successful. About 95% of my work was in the software, but a=
 hardware
device to convert logic levels was also necessary. This device is now=
 commonly
referred to as an SIO2PC cable.

Features:
  -  Emulates 1 to 4 Atari disk drives=20
  -  Store your Atari files on PC hard or floppy drives
  -  Boot from the PC, real drive not needed to start-up
  -  No software or drivers required for the Atari;=20
         no conflicts: use your favorite DOS=20
  -  Twice as fast as an Atari 810 drive and more reliable
  -  Co-exists with real drives in the Atari daisy chain
  -  Compatible down to the hardware level: use sector copiers, etc.
  -  Print-Thru captures Atari print-out and routes to PC's printer
  -  Convert Atari files to PC files and vice versa
  -  1050-2-PC version connects PC directly to Atari disk drive

David A. Paterson writes:

"Steven J. Tucker took SIO2PC one better and wrote new software.
The Atari Peripheral Emulator (APE for short):

- lets your PC act as high-speed drives.
- It lets you print to your PC printer.

Subject: 10.8) How can I connect my 1050 to my PC with the APE ProSystem?

The APE ProSystem goes beyond APE.  The ProSystem has two components:

- The program PROSYS.EXE is used to create the protected and unprotected
disk images which are then used by APE.

- The ProSystem hardware is a cable designed to allow direct connection
of a stock 1050 disk drive directly to a PC's serial port for use by the
PROSYS.EXE software.

The words are theirs, not mine.

How Atari Got It's Name
-----------------------

The name Atari actually comes from Japan.  And yet the company is most
definitely American.  Every wondered why?  It's an interesting story and
one well worth telling.

In 1972 three friends decided to invent and market the first commercially
feasible video game.  They were Nolan Bushnell, Ted Dabney and Larry Bryan.

To become a partner each man had to submit $100 to the project - a
remarkably small sum when you consider the company's success!  The next
step was to find a name.

Drinking beer and thumbing through the dictionary one day, the three
friends came across an interesting entry under "S".  The word was Syzygy,
or "the straight-line configuration between three celestial bodies".  What
a perfect name they thought, for three such astronomically talented people!

Now they could get on with the business of inventing games.  Their first,
Computer Space, was produced and all seemed to be going well.

But then things started to get a little shaky.  Larry Bryan decided not to
ante up his $100 and pulled out, leaving Bushnell and Dabney to go it
alone.

The set up a shop in Santa Clara, California, and incorporated the
business.  A little later they invented Pong.

Busnell and Dabney applied for the name Syzygy to the Office of the
California Secretary of State, which regulates Californian corporations,
but were told that they were too late.  The name was already taken.

Following unsuccessful attempts to buy the rights to the name from the
first Syzygy corporation, which appeared to be inactive, the friends'
solicitor pressed them to think up an alternative.

This proved difficult.  BD Inc and DB Inc were tested and then rejected in
turn:  the first bore too close a resemblance to Black & Decker, the second
to Dunn and Bradstreet.

Inspiration occurred at last, once again in an informal atmosphere.=20
Bushnell and Dabney were both keen players of Go, a Japanese strategy game,
and their best brainstorming always occurred over a good game and a bottle
of beer.

This time, they decided to make a list of several Go words to see if one of
them would fly as the new corporate name.

First choice was "Sente", which means "the upper hand" - something that
greatly appealed.  Second and third choices were "Atari", which has a
similar meaning to the English word "check", and "Hanne", an
acknowledgement of an over-taking move.

Busnell and Dabney submitted the list once again to the Office of the
Californian Secretary of State, which approved "Atari".  The rest is
history.

When the company name changed, Bushnell and Dabney decided to update the
logo too.  They incorporated the "S" from Syzygy and the "A" from Atari
into the new design.

It was not until later, as the company became increasingly successful, that
an advertising agency designed the slicker and now famous Atari logo - the
"fuji" or stylised "A" design.

Subject: 11.2) What is the History of Atari?

Here is a very condensed history of Atari, centered around their 8-bit
computers.

1972=20
Atari Inc. is formed by Nolan Bushnell, incorporated on Tuesday, June 27.
Atari created the first coin-operated arcade video game with the=
 introduction
of Pong. The video game industry was launched and has shaped pop culture=
 ever
since.

1976
Warner Communications acquires Atari Inc.

1977
Atari launches the Video Computer System (VCS), later known as the 2600,
giving
birth to home video game systems.

1978
In December, Atari announces the Atari 400 and 800 personal computers, using
the 6502 microprocessor.

1979
Atari files with the USPTO for a patent for a "Data processing system with
programmable graphics generator" (the 400/800 computer system) on=20
January 8, 1979.  Inventors listed:
  Mayer, Steven T. (Auburn, CA);=20
  Miner, Jay G. (Sunnyvale, CA);=20
  Neubauer, Douglas G. (Santa Clara, CA);=20
  Decuir, Joseph C. (Mountain View, CA)

The Atari 400 and Atari 800 Home Computers debut at the Winter Consumer
Electronics Show (CES) in early January.

Jerry Jessop writes:
  "The first official small shipment of the 400/800 was on August 29th 1979.
  These were hand built pilot run units to Sears that needed to be in stock=
 by
  Sept. 1 so they could be placed in the big fall catalog. The units were=20
  placed in the Sears warehouse and then immediatly returned to Atari after
  the "in stock" requirment had been meet.

  The first "real" consumer units were shipped in Nov. of 79 and were 400's=
 to
  Sears followed very shortly by 800's."

All Atari computers are tested at the factory by a master computer called=
 the
Atari Sentinel System.

1981
=46rom Atari Connection magazine:
"At the National Computer Conference in Chicago on May 5, 1981 Atari=
 announced
that the 8K Atari 400 was being discontinued and that the price on the 16K
version was being reduced to $399."

The USPTO grants U.S. Patent 4,296,476 to Atari on October 20, 1981 for the
400/800 computer system.  Read the full text of the patent here:
http://makeashorterlink.com/?M2561456

November: 400/800's begin shipping with the new GTIA chip in place of CTIA,
increasing the palette of simultaneously displayable colors to 256 and=
 adding
3 new graphics modes.  CTIA is totally phased out by the end of the year.

Jerry Jessop adds:
  "The very first proto systems did have the GTIA, but it had some
  problems and was not released in the consumer version until 1981. The
  GTIA was completed before the CTIA."

1982
The introduction of the 1200XL in late 1982 marks the single largest advance
in the 8-bit Atari system.

1983
In 1983 Atari replaced the 1200XL/800/400 line-up with the new 800XL and=20
600XL.

1984
Warner Communications sells the Consumer Electronics and Home Computer=20
divisions of Atari Inc. to Tramiel Technologies on Monday, July 2.

Atari Corporation is formed by Tramiel Technologies and its products=
 marketed
under the Atari brand.

 (
   Warner initially retains the arcade division of the former Atari Inc.,=
 and
   renames it Atari Games Corporation.  Soon thereafter, Atari Games is a
   private, independent entity, though Warner remains a major investor.

   Atari Games inherits Atari copyrights/trademarks/patents for use in the
   coin-operated arcade video game market.

   1987

   1998
   In April of 1998 WMS spins off to shareholders its entire stake of Midway
   Games, making Midway Games essentially an independent entity.  Atari=

   1999
   Atari Games releases San Francisco Rush 2049.  This turns out to be the
   last coin-operated arcade game sporting the Atari Games name and logo.

1985
The new Atari Corp. delivered on its promise to advance the 8-bit Atari=
 system
by replacing the 800XL/600XL with the new 130XE and 65XE in 1985.

According to Atari Explorer magazine, the 130XE was engineered by Jose=
 Valdes.

1987
In a change of marketing strategy, Atari introduced the new XE Game System=
=20
in 1987.  Despite its label, the XEGS is a true 8-bit Atari computer system.

1992
Atari (US) officially dropped all remaining support of their 8-bit computer
line on January 1, 1992.  (Some 800XE's were still being manufactured in=
 China
in 1992.)

1996
On July 31, 1996, in a "reverse merger," Atari Corp. purchased JTS, with the
new parent company taking the JTS name while Atari was immediately=
 designated
a JTS subsidiary.  JTS Corp., with headquarters in San Jose, Calif., was
founded in 1994 to design, manufacture and supply enhanced-capacity hard=

1998
On February 23, 1998, JTS sold its Atari Division to HIACXI Corp., a wholly-
owned subsidiary of Hasbro Interactive, Inc., which was a subsidiary of
Hasbro, Inc., for $5 million in cash.

(JTS filed for Chapter 11 Bankruptcy Protection on December 11, 1998, and
then converted it to Chapter 7 on February 28, 1999)

Hasbro Interactive produced games for several platforms, including PCs
running MS-Windows.  Some of Hasbro Interactive's games, including several
re-makes of classic Atari titles, were marketed under the Atari Interactive
name and logo.  Atari Interactive was termed "a Hasbro Affiliate."

Games produced by "Atari" under Hasbro ownership included:
Atari Arcade Hits 1 & 2, Breakout, Centipede, Missile Command,=20
Nerf ArenaBlast, Pong, Q*Bert, The Next Tetris, Atari Greatest Hits

2001
On January 29, 2001 Infogrames Entertainment announced completion of its
acquisition of Hasbro Interactive from Hasbro, renaming the subsidiary
"Infogrames Interactive."  The purchase included the Atari titles and
intellectual properties (known at Hasbro as "Atari Interactive").

Between 2001 and 2003 Infogrames placed the Atari brand on some of its
"premiere" gaming titles.

2003
Beginning May 7, 2003 Infogrames Entertainment adopts the ATARI brand and
registered trademark for all operations, effectively changing the name of
the entire company to ATARI.

Additionally, the Company's wholly owned subsidiary, Infogrames Interactive,
