i have been married to my wife for 5 years, we have been living with her parents for 7.5 years, my wife told me she had an atari in the attic, i didnt really think much of it, she had ~15 2600 carts down here in the storage/garage... well today i went up there and looked... wow... found a mint condition 800xl, 1050, 1027, and time management disk, database disk, and atari writer cart, along with 30 blank floppys, and a composite color monitor... add to this the other day my neighbor gave me a SX-64 (works except for no kb cable) been a good week :') hopefully my eprom/gal programmer will come in this week and it will be like christmas :')

Woohoo for christmas in november!

I'd love to hear if that 1027 printer works. I have one but can't get it to fire up (??). Nice find! A whole rig with games and plenty of disks, nice

Welcome, congrats, and I hate you with all of my being..

And I mean that in the best possible way...

Yes, I'm sure some people hated me when I was given some things....

But I have no perspective, so I choose to just hate you!!!

Well, OK, maybe not, but that is a GREAT WEEK!!

You waited seven years before going up to the attic?

Unless you live at thenorth pole, I wouldnt put any of those floppies in any drive of mine..

I think he lives at the South Pole. Also I think his wife was using the Time Management software that he found and had it scheduled when she would tell him.

nah, she told me years ago when we were dating so i didnt think much of it, and then when i saw the 2600 carts, she said 'o those are some of my atari carts' so i figured the 'atari' in the attic was a 2600... well i went up for something else, and looked while i was there and opened the box and it had an aura around it (had a spongebob moment ) and was like 'foley sheet'... i am sure the disks are deteriorated, we are at the jersey shore so it gets hot as up there as it does 'down' there...

desiv, i just have one thing to say...
'Ha HA, i got a free A8 and you didnt ;'P'

Well, if you happen to find any schematics in your attic for adding SRAM into A800 ROM module, let me know. I have been trying to plug in a HM6116 2K SRAM into the FP ROM socket and can't get it to boot up. It boots up fine without the FP ROM or even with an A5200 ROM in it...

well my first hardware project i am considering is something for the 800 (my first atari, and first love, second being 1200XL) and if you make a small circuit board with sram with battery backup and copy the fp rom to it, it will work...

which reminds me i need to open up my 800 and see if the 802 is still in it...

If you have the schematic of the ROM card for A800, let me know where you get the W* (write) signal to feed into the SRAM.

the OS connector probly doesnt have the r/w signal on it, you will have to get it from one of the ram slots... i dont see my hardware ref here handy, the binder i thought was it, was some C tutorial docs... but you can find them here on AA, which would probly be a good idea to have...

R/W- is on pin 1 of Z402.

Hint: You can't have pins 18, 20, and 21 connected to the socket.

I pulled out pin 18 of SRAM and connected to pin 20 and left pins 20,21 in the FP ROM socket, but I couldn't get Atari to boot up. I thought it would read the data at least and I would modify pin 21 (W*) for write later. What connections do you suggest for pins 18,20,21 of SRAM (for read/write)?

It's not going to boot up because the pin-out obviously isn't the same and the SRAM is getting enabled when it shouldn't be. You need additional logic to make it work:

WE- = not (PHI2 and not RW)
CS- = not (A11 and A12 and not Y6)


A11 = pin 18 on socket
Y6- = pin 20 on socket
A12 = pin 21 on socket

CS- = pin 18 on SRAM
OE- = pin 20 on SRAM
WE- = pin 21 on SRAM

CS- and OE- are tied together.

Simplest is to use a single 'LS139.

1 = GND
2 = PHI2
3 = RW-
5 = WE- (to SRAM)
8 = GND
9 = CS- (to SRAM CS- and OE-)
13 = A11
14 = A12
15 = Y6-
16 = +5V
