There were alot of AT&T codebase ports to x86 architecture except Xenix:
Microport, INTERACTIVE, Everex, Wyse e.t.c. using AT&T x86 syntax.
I've tried Microport SystemV /386 (SysV R3.2). It uses COFF
as format for executables:
See:

(Rather interesting kernel ABI/Call convention)
and

There were also SystemV R2 to i286 ports i.e.:

with a.out binary format.
