Larry & Dave, thanks for jogging my memory. I'm pretty sure it was BDS C on
that z80 Zenith computer. (See my longer post above.)
I should add that around 1984 I got a copy of PC/IX for the IBM XT,
directly from Interactive Systems in Santa Monica, where I knew a few
people. That was true UNIX, System III, I think, and I used it for all of
the examples for my book "Advanced UNIX Programming," which came out in
1985. It, of course, had a real Bell Labs C compiler.

For no good reason, I've been wondering about the early history
of C compilers that were not derived from Ritchie, Johnson, and
Snyder at Bell. Especially for x86. Anyone have tales?
Were any of those compilers ever used to port UNIX?
MIT had several that were used for ka9q and at least the Venix x86
port. They supported the popular micros of the time. Various
versions of them survive to the present day.
It's at bitsavers:

are pointers to compilers from the early 80s. Obviously not ANSI-C
compilers :)

When I only had PC/IX on an XT at my office and a PCjr at home, I mostly
worked with C at home with DeSmet. I still have a couple of 5.25" 360K
diskettes labeled C-Ware, which I think are DeSmet 2.4.
