I've been amused by the talk of Sys V Rel 3 in this group as
well.  The UNIX-PC software is almost certainly based on System V
Release 0.  Our original manuals for the 7300 mention SVR0, and
lots of other signs abound: /bin/sh has no shell functions, the
miserable curses, the old archive formats, and the dates found
in various system files.

My primary experience is with UNIX-PC Software version 3.0, and
it looks *very* much like SVR0.  Velease 3.5, which I am only
slightly familiar, seems to be a lot better (terminfo, etc.).
Nevertheless, I find it highly improbably that AT&T (or
Convergent) built 3.5 from fresh SVR2 source; they likely just
added the user-level utilities to Release 0.  The only real
SVR3-ism I see in the UNIX-PC is the shared library facility.

Rebuttals of this are encouraged.
