I’m working on a Stern Lectronamo. It wouldn’t boot in the game – missing 5 volts at the MPU. I have 5 volts at J4 so I pulled the board out and tested it on the bench. It booted fine. I need to replace the headers so I was looking it over so see what else needs to be done. That’s when I noticed that C80 is totally missing!

This board has been worked on before but I see it needs a lot of help. I just thought it was strange that it boots with missing parts.

You mean it's NOT the original board? I'm shocked. Just kidding - seldom do I find a game with the original boards. But how can you tell it's Bally and not Stern?
