If anyone is interested in trying to develop drivers/code
for a SunPCI PC CoProcessor Card, I have one that I would
be glad to part with.  Not sure what speed Pentium is on
the thing, and it has one DIMM on it with eight Hyundai
HY57V658020 chips on it, Part# HYM7V65801 -- 8M or 64M?
Not sure.  ESS1869 Audio chip on board.  Don't even know
if it works... but its yours if you have a desire for it.
Free, which is the price I paid for it :-)
