3B1 Power Supply pinout wanted.

[julian macassey]

        I now have my spare 3b1 Power Supply from Halted 
Specialties. What a bargain. My original plan, before these 
came along, was to replace my 3b1 Power Supply with a Generic 
PC-Clone Power Supply when the 3b1 died. This would have been 
messy, with an outboard PSU and cables, but would have kept me 
running. 

        Now I look at my spare 3b1 supply and say to myself: 
"This sucker is pretty cheap and would probably make a great 
PC-Clone Power Supply." 

        Whichever way I go, I need to know what voltages appear 
on what pins on the Power Connector. The Hard Drive Connector 
is the same one used on MS-DOS machines, the question is the 
0.1ins 18 pin connector that carries the DC to the mother 
board.The connector is marked as J1. Looking at it from above 
with the connector closest to you it looks like this:

     o  o  o  o  o  o  o  o  o  o  o  o  o  o  o  o  o  o
    18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1

        Could some kind soul who is in the know let me - and 
possibly the net - know what voltages appear on these pins and 
what current each would supply. I know the total current the 
board can supply is: 20A @ +5V, 5A @ +12V and 0.3A @ -12V. But 
where does it come off is the question.

Yours, still on the lookout for 3b1parts.
