I seem to recall that Definicon made coprocessor boards (68000 series, and
maybe 32016 series as well) for PC's. You rean special language compilers
on the PC that converted your high-level source into machine code for the
68000 or whatever, and ran it on the coprocessor board

It didn't (AFAIK) emulate any other standard computer - for all there was
a 68020 in there, you couldn't run Mac (or Amiga, ST, or whatever)
software on it. The rest of the machine was totally different.

There was an article about them in Byte, sometime in the mid 1980's. I
seem to remember it gave partial schematics for one of the boards. Don't
ask me which issue it was, or where to find it...
