But even then, all is not lost.  There is a simple, inexpensive adapter 
available to translate PS/2 to XT for just such purposes.  Uses a little 
Atmel microcontroller and a handful of other parts.  If anyone is 
interested, ping me and I'll dig up the URL.

As I can't find an old AT keyboard at the moment, I'm trying to get one of my old Coco 3 keyboards to work again. I opened the coco keyboard and cleaned all the contacts and reassembled. Dead keyboard. Upon further inspection, there seems to be a trace on the ribbon cable coming from the keyboard that is broken. It's the very first trace on the side that has 2 traces then a missing trace.
