I was wondering if there is an easy way to test and adjust the +5, +12v, -5v on the midium power supply.

I mean is there an easy way to meter off the caps like for the mcr power supply?

I was able to adjust the +5v on the j3 connector. But it seems like metering the +12v, on the connector moving the adustment pot has no effect (probably has to do with the sense line).

I just got a super pac with the conversion kit to jr pac and the pcb looks doa. So another question I have is how close is jr pacs pinouts to pacman? I think I read its very close to dc galaxian..
