The schematics and PCB layout are available here (87 K zip file).

The adaptor has been tested with a number of ATX power supplies, all worked without issue. The only clarification I would make is relating to the on/off timing.
To turn on/off, depress the case switch, count to 1, then release. It is the release of the power switch that triggers the circuit, this is subtly different to the operation of a PC.
