Ian:
According to my motherboard manual, the AT coding is:
        Pin 1: power good - Orange
        Pin 2: +5v - red
        Pin 3: +12v - yellow
        Pin 4: -12v - blue
        Pins 5, 6, 7 and 8: Ground - black
        Pin 9: -5v - white
        Pins 10, 11 and 12: +5v - red
I couldn't find anything about the ATX color coding. If you don't have
access to an ATX machine, perhaps a visit to your local computer store
might be fruitful. You might want to check out Trish's Escape from
Hardware Hell. Sorry, but I don't have the urrl, but some search engine
should be able to find it. Trish maintains a large list of hardware (and
software) sites sorted by category, and can be a very useful resource.
HTH, and good luck on the diploma.
