Kind of scratching my head here. I have a GTB Hot Shots here that I am working on that continually corrupts the high scores (and audits for that matter). The game is 100% functional other than that. The 5101 has been replaced with a known good one and the problem exhibits itself regardless of having backup batteries in place or not. The resistor at TC1 to help with memory issues is present and accounted for. Going in to the audits, I cannot use any of the switches to clear the high scores.
Any suggestions as to where I should look next?
