on them? But of course! Opus Systems, like Definicon, put a couple of different CPUs on full-length ISA cards that would be added to or bundled with PCs to create a lower cost workstation in the latter half of the 80s. Opus delivered products using the Nat Semi 32000 family, later developed the Personal Mainframe Series 8000 using an 88k chipset, and eventually did it again with SPARC. We had one of these 88k boards in a Compaq DeskPro on a researcher's desk in 1991 and he was quite pleased with it. If one of these 32k or 88k systems/boards should need a new home, feel free to give me a shout. ;^) /Los links!!/ - All of the following shortened links go to Google Books.
