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.
