I just meticulously restored a Rollergames and got one whole day out of playing it before the drop target reset stopped working.
I tested the coil, which gives me about 3.9 ohms' resistance. I'm still having trouble with this damn game. I know the transistor is good, as the associated flasher is working. Diode in the Aux driver board tests out OK and matches the diode in the same location on Diner (another system 11C I own). Fuses in the Aux driver board are OK, according to continuity test.

This is making me nuts. Can anybody give me some insight as to what's going on here??
