No. That one sounds like the special keyboard interface card for the
PC/3270. There is a special keyboard cable that connects to one of the
9-pin sockets and also to the 5 pin DIN socket on the system board. I
can't remember what the other socket is for (mouse?). That card should be
a single full-length card with an Intel microcontroller (8048 or 8051
series - I forget) on it.

The PGC is _2 boards_ I think (Philip: I don't recall a 3rd board being
mention in the manual). It plugs into 2 adjacent full-length slots on the
system board. It contains an 8088, some RAM, video chips, and TTL glue. It
has a special double-width fixing bracket at the back.

There is one DE-9 (9-pin D) connector on the back.
