Re: [TUHS] Thompson at Berkeley on an 11/70

McKusick wrote that the 11/70 arrived in Fall of 1975 and it was installed with Version 6. (Marshall Kirk McKusick. A BERKELEY ODYSSEY: Ten years of BSD history. Unix Review. January 1985. Volume 3. Pages 31-42.) But the Quarter Century book (page 155) says it was upgraded to V6 after Thompson left (he told me he left right after exams in June). Thompson told me he brought up the 11/70 for the EECS (but didn't tell me the version). (Jolitz and Allman told me the shared 11/45 also used for CS classes ran v6 (and RSTS-E) but I don't when it was upgraded to v6. The INGRES group also their own dedicated computer which ran 5th Edition and then v6.) (Thompson told me that he wrote his Pascal between quarter 1 and quarter 2 and that Fabry used it for his instruction the next quarter. Fabry told me that Thompson's students completed their programming assignments using the Cory Hall PDP-11/70 running Unix.) O'Brien suggested to me that the annotated fifty changes wouldn't apply to Berkeley's already hacked kernel. Allman and Fabry told me that in their code reading sessions, Thompson had the John Lions' annotated code for the v6 kernel. I believe these (Lions') lecture notes were from May 1976 (so not much time before Thompson left). Thank you so much for pointing me to this. Too bad there aren't dates mentioned in the code or diff files. I am authoring a book that includes this same story (and I had basically the same questions). Jeremy C.
