I received some power supplies and got 1 of the 3 working. 1.) ComPaq PDP-100 - no idea how to hotwire it 2.) CompUSA - worked when I hot wired it, seperated all the wires and capped off unused ones. Go to turn it on and the fan jiggles for a split sec but won't power up. 3.) working so far I just can't swallow Ray's shipping costs to get them from him.
