Compaq power supply needed

I have a friend with an OLD Compaq 5260 computer, in which the power supply has failed. It is an ATX style supply, but has three AT type 6-pin connectors to connect to the MB, just to make life difficult. The computer is very old, I admit, and have pointed this out, but...

Any chance that someone has one of these, working or not, lying around? There is a possibility that I could repair his supply, if I had another one for component identification. There are two shorted zener diodes that are a mystery as to their voltage. Maybe other things too.

I'm in Auckland. Thanks for any help.

Gosh, I haven't seen one of those for a long time. I'd say you'd be pretty lucky to find one.
