it's 15 pins in a 3x5 matrix: http://frokostgruppen.dk/~bjuhn/stik.jpg
the one i've found is in an ibm risc system 6000 i picked up. the psu was missing, so i wonder if i can solder wires from an atx psu to the motherboard connector[/img]
My commodore PC10 computer has the same PSU connector maybe that can help?
