SDS940 connection

The first/main TENEX paper ("TENEX, A Paged Time Sharing System for the PDP-10", by Bobrow, Burchfield, Murphy and Tomlinson) specifically calls out the 940 as one of the systems they used as a model. Jnc (talk) 17:17, 29 March 2018 (CEST)

Also, according to "TENEX and TOPS-20", by Dan Murphy (IEEE Annals 37-1, pp. 75-82), BBN actually for a number of years had a 940 with the Berkeley OS on it; so they would have had personal experience with it. Jnc (talk) 17:28, 29 March 2018 (CEST)

Thanks. I did check the Murphy papers, but it doesn't explicitly say that parts could be a close translation, which is what I find interesting. Hopefully, the 940 sources will be available soonish. Larsbrinkhoff (talk) 18:23, 29 March 2018 (CEST)

Hierarchical file system?

I'm not sure, but I have the impression there was no directory hierarchy. Murphy's paper says "We are currently considering the feasibility of implementing a full tree directory structure similar to MULTICS". Budne's TOPS-20 Evolution says it was added in TOPS-20 V3; I have verified this running V3A. Larsbrinkhoff (talk) 10:09, 21 April 2022 (CEST)

Oh, could be. I assumed there were because of my use of TOPS-20 (on MIT-XX) which had them, and since TOPS-20 was based on TENEX... Let me check it out in the TENEX docs (Dan Murphy's site has the ACM paper - I think I have a photocopy somewhere I made 4 decades ago! :-), and then I'll fix the page.
