RAM chips and Intel 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.
Intel 82586 is an Ethernet controller, DA15S is the right connector
for an Ethernet transceiver, and Bridge Communications got bought by
3Com in 1987. I think you've got an intelligent Ethernet interface of
some sort.
