Not quite: more accurately ( 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. -- -john mashey UUCP: {decvax,ucbvax,ihnp4}!decwrl!glacier!mips!mash ARPA: mips!mash@SU-Glacier.ARPA DDD: 415-960-1200 USPS: MIPS, 1330 Charleston Rd, Mtn View, CA 94043
