OK, after testing I do appear to have a short somewhere. Both the -5V 
and -12V lines appear to be shorted - using the continuity tester, I get 
a continuous beep between these lines and ground. When testing the +5V 
and +12V lines, I get no beep at all (which is what I would expect for 
all lines).

So I guess I'll need to trace back through the -5V and -12V lines and 
find whatever it is that is causing the short. I hope it's something 
fairly obvious, as I'm a software guy by day - and whilst I'm 
comfortable enough with a soldering iron and multimeter, its certainly 
not my area of expertise.  ;-)
