In article <picc8e$360$2...@dont-email.me> you write: >One tended to be overawed by the PDP10 series, but I wonder if >its operating systems would seem rather infra dig compared to Linux >today? In terms of number of features, linux wins by a parsec. In terms of getting useful work out of a computer that ran at about 5MHz (yes, I know the KA was async) and had 1MB of core, TOPS-10 wins just as much. It had features that mattered then but don't any more like doing disk I/O directly in and out of buffers in user space without an extra copy. I could have done without the sequence numbers with the flag in the low bit of the word, though. Of course, even TOPS-10 was a pig compared to DTSS which ran on a GE 635, about the same speed as a KA-10, with a very slow front end terminal mux (sort of like a 680) and provided good performance to 100 users. -- Regards, John Levine, jo...@iecc.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
