|At ZDS I had worked on putting Unix v6 on the Z100 (but never finished).
|What got me excited about doing it was the protected mode of the 286 chip,
|and it's support for virtual memory (and a larger memory capacity overall).
I wrote a fairly comprehensive unix kernel clone for the Z100 (most of the
4BSD API less the networking). Later I ported it to the IBM PC and later
still to the protected mode of the 286 on the AT. I even wrote a DOS
emulator that was good enough to run the Microsoft C compiler so I could host
a compile of the operating system under itself. (Unfortunately, the emulator
didn't support the 286 version of the OS. :(). It was called OS/88 and might
still be floating around, or I could dig up a copy...
