I've got an issue with a Centipede board I have. It randomly beeps when in game play (the same beeps you hear when in test mode). There is no rhyme or reason to when they happen and occasionally the board will reset.
I've swapped a working board into the cabinet and the problem is gone. I've also swapped in another good ARII power supply with the faulty board and the problems are still there.
So, I've narrowed down the problem to something on the board. I've swapped the following chips: 6502 (C2), 2P, 8126 (4D) and the problem doesn't change. I've also double checked voltages and cleaned & checked the connectors/edge connectors.
Is there any advice or pointers that could help me from this point?
Thanks!
