The header at the top is labeled:

In that supply
room, there are about 25 shrink-wrapped boxes of somethin
called "IBM 3270"; I was wondering what it was-have no clue myself.
It might go with the 11 full length 8-bit IBM PC cards, that have BNC
connectors on them. This is why I asked what an IBM 370 was earlier-
it acts as a host for this.
I have what I believe to be an interface card from a 3270 PC here. It's a
full-length 8 bit card with PC/3278 on it. The main chips are :
N8X305N (microcontroller)
3 off ROMs (15527-15529, Copyright 1983)
4 off 6116 RAM
DP8340 and DP8341 (Some kind of interface chip...)
Assorted TTL glue
Passives, including a reed relay
There's a single BNC connector on the bracket. There's also an expansion
edge connector at the top front, which seems to be linked to the ROM
pins/the microcontroller.
