I recently acquired an OPUS 300PM. It appears to be
a Fairchild Clipper computer on an ISA card. I have
absolutely no documentation or software for this card,
but would love some!
Clicking on any of the images will bring up the full-size photo.
The second, smaller daughter board is silkscreened CLIPPER and FAIRCHILD with a part number of AM76400AAAL.01-D. There are three large chips on the top side, two of which are stamped:
The other is stamped:
Any information, software, and/or leads on where to find out more about this board are very much welcome!
Will Jennings was kind enough to send this:
Indeed, the Opus PM 300 is essentially a Clipper chip on an ISA board.. FYI, the Clipper processor is technically all 3 of those chips on the daughter board, so calling it the Clipper "chip" is slightly innacurate, but hey. Unfortunately, I don't know a lot about the thing, other than that OPUS made several different plug-in boards like that, I know they made one with the NS 32016, one with the 32032, and I've seen one with a SPARC too.. The purpose of these boards is to run *NIX on a PC.. Don't remember what flavor *NIX it was, either... Also, the PM stands for "Personal Mainframe". Check old BYTE magazines for ads.
