trying to identify this 68K-based board...

It is an ISA-16 card. It has a 68000, w/2 27128 EEPROMs, 16 1259-15 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. 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? Eric
