The OS done for the 6/32 at CCI Office Systems Group was basically "4.2BSD
as it would have looked had it been based on S5R2".  S5R2 programs that
didn't depend on directory entry formats, file system layout, or internal
kernel data structures compiled and ran.  4.2 programs stood a good change
of running, although if you expected "sprintf" to return a pointer to its
buffer or expected RAW mode to work 100% like the 4.2BSD one you'd be
disappointed (the S5 "sprintf" returns a count of characters printed, and
RAW mode can't be simulated with an S5 driver without adding some extra
hidden state) - all the other 4.2BSD stuff except for useless stuff like
LTILDE was there, though.  The software group in Irvine put the System V IPC
mechanisms into 4.2, so they are there also.

This was what we had running on the VAX at CCI OSG.  I don't know what
subset of 4.2BSD facilities was present on the 6/32 (there were some things
that weren't there when I left) or what set of the facilities in the OS we
did ended up in the final system (that system is still being worked on, I
think, so the final cut hasn't occurred yet).
