What's the risk? FWIW, I did the PS/2 -> AT conversion on the IBM 
keyboard I am typing this on.

I seem to rememnber I couldn't find the PS/2 pinout at the time I was 
doing it. I did (of course) have the PC/AT one. I opened up the keyboard 
and buzzed out 2 of the wires to the power pins of a known chip. Those I 
soldered to the right pair of pins on the DIN plug. The other 2 wires, 
clock and data, are both open-collector driven bidirectional TTL signals. 
You can try those one way round on the clock/data pins of the DIN plug, 
when it doesn't work ('press F1 to contine' :-)), power down and try them 
the other way round.

How about a hardware guy with a C compiler :-)
