I deleted the PDP-9 from the list of systems. It wasn't one of the main development platforms. According to this note from Dennis Ritchie, it was only run on a PDP-9 for a few hours to play around. Since it says the PDP-9 belonged to a "different group", I assume this means it was in another part of Bell Labs other Dept 1127, and thus not strictly part of the Research UNIX project.

Distribution terms[edit]

I assume the code was copyrighted by AT&T, but on what terms was it published to other users? In particular, how did the code legally become part of BSD, which has a free/open source license? -- Beland (talk) 03:12, 4 February 2013 (UTC)

The article Berkeley Software Distribution covers that. All full BSD distributions required an AT&T source license. Only 4.4BSD-lite and lite2 were open sourced (although that term didn't yet exist), but in those versions all AT&T code was replaced. Except for a few bits, that is, which lead to the USL v. BSDi lawsuit. QVVERTYVS (hm?) 12:17, 6 October 2013 (UTC)

Proposed merge with Version 5 Unix[edit]

IMHO, V5 Unix does not have sufficient notability to warrant its own article. The material in Version 5 Unix is already covered by Research Unix. (For this very reason, I merged my own former articles about V9 and V10 into Research Unix.) QVVERTYVS (hm?) 12:18, 10 February 2014 (UTC)

  • Support. I'd probably also throw in Version 8 Unix as well. Only Version 7, as the basis of the first commercial implementations, is really independently notable. 17:28, 9 April 2014 (UTC)
Done. I agree with V8, but before we go into big merge mode, note that actually V6 was the basis for the first commercial versions (and of the Lions book). QVVERTYVS (hm?) 18:46, 9 April 2014 (UTC)
