New PBI HDD

Sun Jan 15, 2012 5:48 PM

I am making a PBI HDD (CF card, actually) that uses fixed block partitions. There would be four standard 'disk' sizes - 1024, 4096,16,384, and 65,280 sectors. They would be written on the disk as 64 - 1024 sector disks, 16 - 4096 sector disks, 4 - 16,384 sector disks, and 1 - 65,280 sector disk. This pattern would repeat out to the end of the card. An 8GB card would then have space for 4096 disks of 1024 sectors, 1024 disks of 4096 sectors, 256 disks of 16,384 sectors and 64 disks of 65,280 sectors - all at the same time.

The advantage to this is simplified disk 'mounting' and automated disk loading. You can load .ATRs from a PC with no operator intervention. Just dump as many .ATRs as you want into a folder on the PC and run the ATRLOAD s/w on the Atari. Go eat dinner, watch Big Bang Theory... when you come back, you have an HDD with a bunch more 'disks' on it.

And, maybe more cool stuff...

Comments? Now would be the time to make suggestions.

M/L to Basic Data Statements?

Sun Aug 28, 2011 6:12 PM

I have some machine language routines that I want to convert to BASIC DATA statements. Isn't there a BASIC program out there that you can point at some object code and have it generate DATA statements that you can then ENTER into your program?

I don't want strings because they are impossible to change easily and I have a ton of memory, anyway.

Where are our PMs?

Title says it all. Where are our PMs? I go to my profile but it just flashes a drop-down and then dumps me. Not nearly enough time to select anything...

512K in a 1200XL

Tue Feb 22, 2011 7:38 PM

This is my latest 512K upgrade for the 1200XL. It requires the 800XL OS mod, 3 more board wires and the 5 PBx wires. (no PCB cuts, so you can remove it easily) You end up with 512K (battery-backed) in addition to the original 64K.

I have a couple of spare boards...
