Scratching my head on this. Beginning work on project Fathom. Installed a working Weebly.com Universal MPU board with dips set for Fathom. Installed a known good solenoid driver board. Installed all 3 balls. Turn on game and after MPU gets 7th flash one feature light comes on, the outhole kicks out one ball, then another, and game freezes there. If I then take a ball and put it back in the outhole, it kicks out 2 times again, then the displays come on and the all the feature lamps come on in attract mode, but doesn't coin up and the credit button doesn't do anything. All 4 switches at the outhole test good and are adjusted. What do you suppose is going on?
