In the October'85 "UNIX System V Known Problems List", which is
basically a printing of filed bug reports against System V, it lists a
'DEC' version of these SVR releases:
SVR1.0V1 (5.0)(1.0) - Initial Release
SVR1.1V2 (5.0.5)(1.1) - Maintenance Release
SVR1.2V3 (1.2) - Maintenance Release
SVR2.0V1 (2.0) - Feature Release
SVR2.0V2 (2.0P) - Paging Release
Each bug's machine type applicability is matched against 3B20, 3B20A,
3B5, 3B2, PDP, and VAX enumerations. I see a few places where a few
VAX11 models are called out explicitly but none specifically applying to
PDP machines. So apparently there was a 16 and 32 bit version of SVR2
supporting some versions of both PDP-11 and VAX-11 machines.
Unfortunately I don't have the entire manual scanned in yet so I can't
search for specifics. But it seems rumors of a pink unicorn abound.
