Just got this game and I'm pretty close to getting it fully working. Only problem left is it won't activate the stepper twice at end of ball in a single player game. In other words, it should step twice to go from, for instance, Player1 Ball1 to P1 B2. Instead it only fires once, sending it to P2 B1. It tries, but there's a switch somewhere not making strong enough to activate the stepper coil the second time. The first activation is a different circuit. Anyway, I was wondering if anybody had the schematic and could help me with this, maybe take a picture of the section of the schematic that deals with this. Thanks!

Thanks Mark! I've been working off of a Lite-A-Card schematic which is a couple years earlier. Neither one is exact, but they both give me ideas where to look.
