I'm trying to restore order to my
junk pile office, and I ran across this card. I am usually pretty good at generally identifying old (PC?) stuff, but this one is outside my experience.
I think it is some sort of co-processor - the card is clearly labeled "X4 Copyright (C) 1988 The Palantir Corporation" and appears to sport a Motorola MC68020 CPU. There is also a 40 pin (if I counted right) unkeyed connector in the center of the card, and two large connectors near what looks like a large block of RAM (I might hazard a guess these might support a daughter-card with more memory?)
Can anyone tell me what this thing is?
