I can't rememebr if it's this machine, but one of the more 'exotic'
original PCs has a somewhat strange keyboard conenction.

There's a card in one of the expansion slots which contains (at least) an
8051 microcontroller. It has a couple of DE9 connectors on the bracket
with one hole (at least) blanked off in each one). There's a 3-ended
cable that connected to one of the DE9s, to the keyboard connector on the
motherboard, and to the cable from the special keyboard.

_Somewhere_ I have that cable, but don't expect me to find it in the next
year or so. If I do find it, I'll buzz it out and post the wirelist.
