Well... when AT&T was doing their original SysV work, what platform(s) do
you think they supported?  Or... which 32-bit VM capable systems existed
in the early 1980s?

That's not the best answer.  I forget who did the original work, but I
think it was around a year ago that someone mentioned doing SysV binary
support for the VAX as contract work.  There are probably clues in the
sources.
