I'm working on a Laser Cue as well that's doing all sorts of crazy things. It will boot up and go into attract mode. When you press the start button the drop targets will do several re-sets the bell starts ringing and then sometimes crash sounding like the sound is winding down.. If it doesn't crash and you push one of the standup targets it then crashes. Before it crashes the flippers work, slings etc. Only the outhole kicker will not load a ball into the shooter lane. The driver board is a good re-built with new female pins for the two boards to connect. The MPU has had no work. If you push the MPU test button a 9 is displayed. The game had the wrong out hole kicker coil without a diode. Could this have damaged the MPU? Also the connectors on the left side of the MPU aren't keyed and were off the board. Can someone tell me the correct placement? There is a black wire connector, brown, and 2 more I believe mixed colors. I want to double check even though they pretty much fall into place with age. Thanks!

Yes I already know that. Could that missing diode have toasted the IC?
