Back to the Duo Dock logic board "Gemini" logic board PSU connector pin out. I found a couple of sources. 1st, a picture of the PSU connector to the logic board showing the wire colors. 2nd, a forum post where someone troubleshoots a PSU. I've confirmed the GND, +5V, and +12V pins correctly (SCSI power) but I can't be sure of the others. What do white, yellow, brown, and light blue wires typically do in an Apple PSU of that era? #RetroComputing #VintageMac
