I'm looking for scans of documentation for the System 1 arcade board. I have some homebrew software up and running:




But I don't have any info on the 6502 program that controls sound, coin acceptance, and the 6522 VIA. The only documentation I have is a 14-page general hardware description retrieved from the offices of Atari's Ireland office and the MAME source. I know there used to be sites with lots of scanned internal documents but I'm not sure where they went...

I wish I could help you with that... I've always wanted to program the Atari System 1, but my skill level isn't there yet. You might have to make your own sound driver for that thing or try and get in contact with someone who's familiar with MAME's version of the System 1 emulator driver. Until then, here's a few pdf files I have on it including the "Ireland info" minus a couple of pages at the end. Hopefully this will help you in some way.


Good luck.

Thanks, the Gauntlet book fills in some blanks from the Ireland hardware description. I was able to write my own BIOS ROM and a basic 6502 sound driver. The demo version from this video I made even got into HBMAME.
