Galaga 88' help converting to a switching power supply
I have an Original dedicated Galaga 88', I would like to replace the existing power supply from 1984 "Astec Components Ltd." with new a switching power supply. Rather than re-wire the entire cabinet with a new JAMMA harness which I can do if I really need to, hopefully someone can help me without needing to do that. The game has it's own weird JAMMA type adapter from the factory. I see where it's connected on the harness it's labeled "Power", but I don't know what's ground, -5, +5, +12, etc... Nothings labeled.
Below are pictures of the inside of my cabinet showing the existing original power supply, along with the adapter I'm referring to. The first 6 wires on the adapter are power.. the ones to the right of it are speaker wires.
