Not quite: more accurately (<bad words> upon the numbering):

PWB/UNIX 1.0  was a Version 6-based system, as was 1.1 & 1.2; only 1.0
was released outside, as I recall [which was too bad: 1.2 was a really
clean, well-tuned V6].

UNIX/TS 1.0 [my manual says Nov 78] was basically V7 + few kernel changes
derived from PWB + some USG Generic 3 stuff. It's goal was to get at least the
time-sharing kernel interface standard. It didn't have SCCS & other PWB
major user-level subsystems, although little things crept in.

PWB/UNIX 2.0 [June 1979] was UNIX/TS 1.0 + the rest of the PWB stuff.

UNIX 3.0 [June 1980] was System III.  Note there was no UNIX 2.0, whose
number was taken by the last PWB release.  Most of PWB/UNIX 2.0 was included.
This is where ioctl & echoe appear.
