From mboxrd@z Thu Jan 1 00:00:00 1970 From: wkt@tuhs.org (Warren Toomey) Date: Sun, 18 Dec 2016 08:34:16 +1000 Subject: [TUHS] Dennis' Draft of the Unix Timesharing System: not so draft? Message-ID: <20161217223416.GA12706@minnie.tuhs.org> All, I'm writing a paper based on my June 2016 talk on PDP-7 Unix. As part of that I was looking at the BCPL -> B -> NB -> C history. And as part of that, I was reading Ken's B manual, written in 1972: https://www.bell-labs.com/usr/dmr/www/kbman.pdf Then I noticed at the end Ken refers to: Ritchie, D.M. The UNIX Time Sharing System. MM 71-1273-4. which makes me think that the draft version Doug McIlroy found (now at http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/UnixEditionZero-Threshold_OCR.pdf) must have made it into a full memorandum. Given that we have the memorandum number, does anybody know if it would be possible to find it in the archives from what was Bell Labs? Cheers, Warren
