Not sure what to do about the power supply, though. The fuse is fine. The first time I switch on, the fan turns about 1/8 of a revolution before cutting out; on subsequent attempts nothing happens except an ominous click from somewhere near the switch.
Some modern power supplies DO require a load. So maybe it does? I used a modern form-factor power supply once to supply power to an external floppy drive. At first the powerpack didn't work except for a slight turn of the fan. I thought it was broken, so I tried again with another one. Same result.
After some web searching I found a discussion which talked about newer power supplies requiring to be plugged into a motherboard in order to activate them (presumably by supplying a load). The advice was that if you wanted to use it just for a periferal device you short out two of the pins on the motherboard connector, (I think it was any black to green). The PSU thinks there is a motherboard attached and activates.
Anyway, I tried this with a paper clip and it worked. The PSU sprang into life and functioned without a problem.
Now please don't follow this advice without doing some more web checking or verifying it somewhere. As far as electronics go, I'm just a very short step up from illiterate. It worked for me with a MODERN power supply, but you might have an entirely different problem.
