It is an ISA-16 card. It has a 68000, w/2 27128

chips, 82586 and 8253-5. The rest looks to be TTL, a couple of connectors and
couple of
crystals, 16 and 20 MHz.
It was made by Bridge Communications, USA, in 1987. And it has a D-shell 15
pin (like a
Mac video -2 rows of pins) female connector on the back.
Just did a Google search on 'Bridge Communications." Had several hits that had
absolutely
nothing to do with computers and electronics, more at the health industry.
Andway, any
info about this card appreciated.
I guess I could through in into an old AT system and see what it does. There
are a few jumpers
marked 'int' and 'address' that might be worth finding out about before
running a "smoke" test.
My guess is that it is some sort of CPU board, but what?

Sounds like an early Ethernet card...
The Ungerman-Bass Ethernet cards are similar in most components except that
they use a '186 processor instead of the 68000
Bridge Communications made Ethernet 'Bridges' and terminal servers before
being bought out by someone else (don't remember who)
