Paxton,
thanks, another suspicion is confirmed:
The 82586 is
intel's intelligent Ethernet controller so I am sure the 15 pin is an AIU
Ethernet connector.
I've never built an Ethernet interface myself, but maybe now I have the
chance to do so. Just need to find some time somewhere. I'll go back and
look where I found the boards... ;-)
With 3 50 pin connectors I think it is a Bridge of
some sort.
You say they made terminal concentrators, too. Could these have had a
Z80 processor, complete with 64k of RAM, for every group of, say, four
serial interfaces, and the processor boards tied together at the 50-pin
connectors? - Then it is indeed "harvest time" for chips. (Picture Robin
Williams as he shouts these words in "Jumanji", during the flower
attack... ;-)
