I don't know about the terminals, but I have a Wyse 386 that was originally designed to use a modular RJ-11 keyboard plug. Someplace I have an adaptor that converts it to a DIN-5 for use with an AT keyboard (moves the 4 RJ pins, and has another wire that clips to the computer frame to provide ground). If it is of any help, I am sure I can find the adaptor and tell you the pinout for it. -c
