Untested, original Atari System 1 Motherboard circuit board from 1985 for Atari's System 1 setup. We haven't tested this board, but assume it will need some repair work as it has been sitting for many years. It is missing two 40-pin ICs on the bottom right corner. Otherwise it appears to be complete and in good condition.
Just not a board we have any desire to try to fix a board like this these days.
See pictures for more details. Listing is for the large, main board as shown. sold as-is, likely needing repair.
