I just picked up an IBM PC3270 with the 122 key
keyboard. The 122 key
keyboard has a 5 pin connector, but the pins are in different positions so
it won't plug into to the keyboard socket as is. I assume there is an
adapter that it usually included. Does anyone have the pinout?
It does boot with a standard XT keyboard, but give a 302 error. It would
be nice to use the original keyboard if I can.
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.
