Looking for a set of the color PROMs for Pole Position 1.
In the process of de-converting a PP2 board back to PP1 and one of the 3 color PROMs broke a leg. Even after attempting to solder on a new leg it's not working properly anymore.
Atari numbers stamped on the chips are 136014-137, 138 and 139. NOTE: These are NOT socketed and are soldered directly to PP1 PCBs.
If anyone happens to be sitting on a set of these, lemme know. Want to check here first before burning new PROMs.
