Definicion did both a 68020 and a NS32032 addon card,
they both did not have a "real" operating system. In addition
to the runtime environment on PC side, they had some native
libraries available, which supported the basic I/O stuff, for the
rest, you were on your own ...

Opus Systems made some PC add on cards as well (with NS32032/NS32332
and at least one variant with a SUN Sparc processor !), they included a
complete Unix operating system ...
... there were quite some manufacturers "in the good times", that developed
such solutions.

I already own some of those boards, but i'm still interested in such PC add-on board
stuff, so if you have one you want to part with, please let me know :)
