Quoted from schudel5:They are all on the same row (white/blue wire).
I'm going to dig into it but one thing I can't find is the diode for the start button. Does anyone know where the diode for the start button is located on Monopoly? It's not on the switch.
From what I can tell by looking through the manual and the pics I have of the CPU, It looks like the diode is somewhere under connection CN7 on the CPU. D400- D407. It has to be one of those. The manual does not make it very clear but that's where it lead me. The diode is a 1N4148 , it's a signal switching diode.
If I'm wrong hopefully someone will clear it up.
