We weren't a unix shop, at the time.  The vaxen were running VMS
(originally 1.6? (RSX utilities) in testing, 2.0 and later 3.0 in production).

The MA780 had installed (INSTALL) compilers and a few other frequently used
applications so they could be shared amongst all the 11/780s.

When I later started at Burroughs, we ordered a 11/750 to run Simula.  More
of an experiment, most of the processor modeling was done on a B7900 in ALGOL.

Transferred to the Convergent Technologies sub in '89, were we had a number
of unix systems (some from the CT side, some from the Unisys side) culminating
in OPUS (64 node SVR4/ESMP single-system image loosely coupled MPP machine).

We built a 88100-based Unix box (S/8400), which sold well in Japan.

SVR4/mk used the Chorus Systemes microkernel and leveraged some of the
SVR4/ESMP I/O drivers, but most of the unix actors (Process Management,
Object Management (e.g. filesystems), Streams Management (SVR4 Streams)
were written in C++.   This morphed into the EEC sponsored project Amadeus
(Unisys, USL, Fujitsu, ICL et alia) to build a distributed version of
SVR4.
