Atari 400 / 800 10K ROM Module - Operating System, Tested and Working:
$25.00

This listing is for the Atari 10K ROM module, the operating system for the Atari 400 and 800 computers. I have 3 of these available, all tested and working. The testing was done by inserting into my working Atari 800 computer and then checking that BASIC loaded normally and that the computer would communicate with my Atari 810 disk drive. This check out fine.
Please note that 2 of the ROMs are in the Module case and 1 is a bare board, as shown in the photos. They are being sold separately, each at the asking price (or best offer).
