And we threw out a couple dozen (at least) of those at work last year.
Ugh. They were Model M keyboards with the extended row of function
keys (or was it an extra row?) AFAIK, they could not be used with
PCs.
Many of the IBM 122-key keyboards can sort of work on a PC if you wire
an adapter and put up with some idiosyncracies. Google turned up
several web pages about interfacing them .They have the same electrical
interface as an AT keyboard, but with a different DIN connector, and
they only support scancode set 2.

I recently got one of the APL ones (IBM P/N 1389194) and I'd like to
pull the microcontroller (probably an 8048 or equivalent) and replace it
with a microcontroller with a USB interface. Some of the
microcontroller vendors have published sample code for implementing USB
HID keyboards, so it shouldn't be too difficult to make it work.
Unfortunately I have eleventy-seven higher priority things to do.
