Beebe) Date: Fri, 5 Jun 2015 11:16:59 -0600 (MDT) Subject: [TUHS] Unix and the PDP-10 Message-ID: This new paper may be of interest to list readers: Dan Murphy TENEX and TOPS-20 IEEE Annals of the History of Computing 37(1) 75--82 (2015) http://dx.doi.org/10.1109/MAHC.2015.15 In particular, the author notes on page 81: >> ... >> The fact that UNIX was implemented in a reasonably portable language >> (at least as compared with 36-bit MACRO) also encouraged its spread to >> new and less expensive machines. If I could have done just one thing >> differently in the history of TENEX and TOPS-20, it would be to have >> coded it in a higher-level language. With that, it's probable that the >> system, or at least large parts of it, would have spread to other >> architectures and ultimately survived the demise of the 36-bit >> architecture. >> ... ------------------------------------------------------------------------------- - Nelson H.
