Talk:Version 7 Unix

First commercial Unix?

"[Wollongong's V7 for the Interdata] was sold commercially under the name Edition VII by Interdata and Perkin-Elmer (now known as PerkinElmer) on most models of the 3200 series, the first commercial UNIX offering"

This contradicts Version 6 Unix, which claims that the first commercial Unix was INTERACTIVE's IS/1. Which one is it? Qwertyus (talk) 16:59, 28 December 2012 (UTC)

It was IS/1, as I remember. I'll see if Teh Google turns up any citations. Guy Harris (talk) 19:59, 28 December 2012 (UTC)

Old-time Unix users?

'Old-time Unix users'? Anyone with a comp sci education appreciates it. Your arrogance was showing. — Preceding unsigned comment added by 2a01:cb18:2ba:e300:6d52:5929:c5aa:c10c (talk) 21:54, 19 December 2018 (UTC (UTC)

New features

Some of the new features listed in this article were not part of v7, but included in PWB 2.0, which was v7-based. Cpio is one of them. Hskrivervik (talk) 06:29, 17 October 2016 (UTC)

Yes, I remember tar, but not cpio, being in V7. Guy Harris (talk) 06:53, 17 October 2016 (UTC)

And cpio was in the V6-based PWB 1.x, as I remember. Guy Harris (talk) 06:57, 17 October 2016 (UTC)

UNIX/32V the direct ancestor of UNIX System V?

32V had a V7-ish API, without, for example, the three-argument open(), without the termio ioctl interface for terminals, and without the run-level based init. Both of those were present in UNIX System III, which was available, at least inside AT&T as "UNIX 3.0", on both PDP-11s and VAXes, as per the internal version of the manual. And, at least according to this System V manual from AT&T, System V "release 1" was available on the PDP-11, VAX, and 3B20S.

So maybe 32V was the ancestor of the VAX ports of System III and System V, but not the sole ancestor of System III and System V as a whole - V7 was probably the ancestor of the PDP-11-specific code, and the rest was probably most the same between V7 and 32V.
