AT Tower Power Supply switch wiring

Help! Am trying to use an old computer power supply to run a CNC
controller. Benchtop dremel machine, Kleinbauer.com NCF2002. Simple unit,
will be using aluminum storefront window frame, but am having trouble
powering up the power supply. Mr. Kleinbauer hasn't seen one like it.

Would like to use an old AT tower-type power supply, 230 watt DC. But,
can't figure out which wires were connected to turn on the supply. It was
from a now obsolete full height tower case which had a line voltage (DPDT?)
switch on the front of the chassis. It has no power switch on the supply
itself but instead uses 5 wires apparently of line voltage size with
individual spade terminals. Which would connect to front of the chassis.
One wire is a ground (green), another hot (white). Two are apparently
reduced line voltage, about 100 VAC (blue, brown). One wire is apparently
the neutral (black).

Anyone have any ideas? B-{)}

thanks,

Gary
