It's two full length 16bit ISA cards bolted together. There's a connection
betwen them. Two EPROMs and several big square chips. No standard FRU number
that I can see anywhere. One of the cards is labeled DISPLAY CONTROLLER.
One of the cards has a 25 pin female connector. The other board has a
connector I've never seen before. It's a D shaped shell which has 3 holes side by
side no more than .25 inch in diameter. In each hole, there's a small pin. What
in the world is this?
That's an IBM RT/PC 'Megapel' video adapter. It used the same wierd
connector as the early microchannel RS/6000 machines. For the time, it
was an extremely sophisticated piece of hardware.
