They were actually pretty good little computers. I still have mine, several disk drives to go with them. Figured might be good brains for a robot or something. Pretty, weird, but I have kept every computer I have ever built or bought, except a 386 I donated to a friend's kid.
Anyway, not all the sockets or holes were filled on the boards, so it might be 'good', but not much use without the power supply or cables. Doubt it would be worth looking for a buyer though, a microcontroller can do pretty much everything the whole board did...
