Thanks for all the links, still looking for just the manual that came with the computer right out of the box, seems like I can find the service manual all over the place, in fact I have the original service manual.

I ordered the most likely key switch from jameco, it wasn't even close.  I tried another vendor, it looked good on the picture, but still wasn't close.  I've searched and searche and to no avail have not found any replacement key switches.  The Power Supply unit seems to be culperit, but once again, hit many dead ends in trying to find any replacements, schematics, or substitues.  I am about ready to throw it in the the garage and forget about it.  If I could find a good substitue power supply that would be good as well.

So let me get this straight
 
The switch was wired with two pairs of wires.  What did the switch do?
 
No key in - Was it just locked off, or was the key board and mouse locked
did it need the key to power up?
 
So Key in had a "C" by the notch,
Then a "0" which I presume was the on position
Then a "R" which was a quick reset but for the computer.
 
So what you are saying is that the key whether wired up or not should not stop the unit from starting up.  If that is the case then it must be the power supply that is bad.
