I've got this ISA card sitting around which was made by Toronto
Microelectronics (TME), but it gives the impression that it may be a
complete SBC in its own right; it has a 386sx for CPU, takes 30 pin
simms, and has various connectors (IDE, floppy, 2x RS232 and parallel
are obvious, then there are another six unlabeled connectors). IC dates
are all around 1993.
I've seen similar Chinese-made NOS ones being offered on eBay. Most of
the connectors should be obvious--including one 10-pin header at the
extreme top left for serial comms. Others should be keyboard, mouse and
probably HDD indicator. A little buzzing out with a continuity checker
should betray the remainder.
I think these were mostly used in passive-backplane industrial
applications. You typically don't need a lot of compute power in such
applications, nor fancy graphics.
