Well, not being familiar with Sun 3's, but recognizing the Clearpoint name,
I'd guess it is a 3rd Party RAM board. Does the board have much of
anything that looks like something other than RAM chips?
As for the low serial number, I've no idea how many Sun 3's were made
either, but I wouldn't read anything into the Serial Number. A 1Mb RAM
board for a Workstation, at that time would have probably cost a small
fortune, and not been produced in very large numbers.
