A bit of a change of topic, I've got a Top Score that I have brought back from the dead, it had been abandoned in a basement for over decade and its history before that is unknown. I'll post some pictures when i get a chance its quite amazing the transformation.
I think i a missing a capacitor, diode, resistor combination that allow the bonus ball time to get kicked up in the backboard. Am I correct? all i have to go on is a line in the schematic and a small 4 hole J connector base mounted on the board near the hold relay. The connector has three wires attached, black, orange-green and white-slate.
I've been going nuts trying to figure this out. Any help would be awesome, and sorry for intercepting the topic, as for the topic i'm just happy to get any points right now....<sigh>
the jpeg was for someone who knows electronics but had never seen a j- connector before so it might seem a bit strange......
