I am pretty sure the Quad-X used the same PSU, but I am not pulling the 
not-quite-complte one out from under my bed to check.

If it is this supply, it's a fairly standard SMPSU giving the normal 
outputs, with a soft power switch. THere are 2 contacts at the front of 
the PSU chassis (connected to a 0.1" 'Minicon' on the PCB) that go to the 
touch switch contacts themselves. TOuching those turns on the relay 
(powered by the NiCd on the board), it's held on by a signal from the 
mainboard, which can then also turn the supply (and thus the machine) off.

I have a hand-drawn schematic of the XXX supply (and the rest of the 
machine for that matter).
