Original Atari Sprint 1 arcade game circuit board from 1976. Listing is for the main board as shown, it is untested, we have no test rig for this game. Boardset is missing a a cap, otherwise appears to be complete. There is some discoloration/white spots near the edge connector, but it is not corrosion and doesn't appear to have damaged the traces.
See pictures for more details on its exact condition.
