I ordered this PCB as non-working. Odd activity, it passed all self tests, had full sound and gameplay, perfect sprites...until about a minute of play and the game would crash. I tried all of the easy things and found this one bare wire on pin 1 of a hd74ls161ap running under the chip. I pulled on it, looked odd and it moved easily. Got the other end from under the chip and now the game does not boot. Any idea one where it should go?
A datasheet on this chip says the wire is soldered to "Clear" It is a ...Synchronous 4-bit Binary Counter. Manual is no help.
