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.
