Very nice! I remember first running this on a 386 pc, and moving from DOS to a gui that can run multiple programs at once was really amazing. Windows 3.1 was ok, and then Windows 98 came and the headaches began.
probably shouldn't plug one of those into a regular motherboard as they would probably try to communicate with the other hardware on the ISA bus and there would be all kinds of conflicts and such. these are made to be used with passive backplanes where one of these are expected to be the main computer that interfaces with the rest of the ISA bus.
