I just purchased a skeeball (old red&white one, I think ModelH) to go with my two mame machines. Everything works except the ball counter. Two wires to the ball counter were broken, so I fixed those but the lower left section on the LED still lights up sometimes so the decode isn't right. It's odd that these wires weren't all taken care of in the PCB. Anyway, I figure it just isn't wired correctly. Does anyone have a schematic scanned in. I know I can probably come across one on ebay, but was hoping to get faster help.
Thanks...
