What chip holds the system clock?
Restoring Pinbot and having weird symptoms I am hoping you can diagnose. There is some faulty logic going on somewhere in the boards I think. Machine boots up fine, press start, game does welcoming sounds and ramp, 3 bank reset, but ball does not show in in shooter for a long time (30 seconds - 2 minutes). If I drop a ball in the machine manually during that time, I can score points but the ball cannot end, and the extra ball hole won't pop the ball back out. After a 30 seconds to 2 minutes, the ball will pop into the shooter land and I can play normally. You'd think it was the roms, but I have 2 sets of U26 and U27 (I have a donor machine) and they have the exact same symptoms. I am on a Rottendog replacement board. I am guessing that one of the chips is faulty, but don't know which one. If I had to guess, I'd say there was something wrong with the system clock. The first ball will take anywhere from 30 seconds to 3 minutes to go into the shooter, and then the next two take exactly 28 seconds... is there an adjustment somewhere I'm missing? I've done factory resets. Thanks!
