Emax

I've got an atx power supply waiting to go into my Emax 1 SE Rack,
since the original PSU went bang. I know there are helpful Emax users
out there who've replaced their power supplies in this way and claim
it's a relatively simple fix. However, I don't have a clue as regards
the wiring. The multi-cable coming from the ATX has different coloured
wires than the multi-cable that connects to the Emax circuit-board, so
it's not a smiple matter of matching them up.

Can anyone put me right? I only had this wonderful machine a week
before the power went. I've heard what it's capable of, but now I left
with a very sad, mute metal box.

Here's hoping...
