@PaSha: Cool. The guy I bought the boards from is looking for the cables; if I can get the originals from him great, if not, I will have an alternative. Can you tell me which connectors on the mainboard go to which on the ports PCB? (There appear to be three of the right type on the motherboard, two labelled short (cn550) and long (cn560) by the keyboard plug, and then there's another one by the roms, labelled cn560 as well.)
