Original Atari System 1 Motherboard circuit board from 1985 for Atari's System 1 setup. This boardset is a little bit of a mess. It looks like someone tried to replace or reflow the solder joints on the large connectors at the bottom of the board and butchered a few traces. We believe that is what some of jumper wires were installed for. It is also missing 40 pin ICs at L18 and K18.
We have not tested it, assume it will need some repair work. Otherwise the board is fairly clean and in good condition.
See pictures for more details. Listing is for the large, main board as shown. sold as-is, needing repair.
