It would be nice if you actually could point out where this is the case. I just went through that 1973 PDP-11/45 handbook, and all it says are "page" everywhere I look. I also checked the 1972 PDP-11/40 handbook, and except for one mention of "segment" in the introduction part of the handbook, which is not even clear if it actually specifically refers to the MMU capabilities, that handbook also use the word "page" everywhere. I also checked the PDP-11/20 handbook, but that one does not even cover any MMU, so no mention of neither "page" nor "segment" can be found. > I figure some marketing droid found out that 'paging' was the new buzzword, and > changed the name...:-) :-) Somehow I doubt it, but looking forward to your references... :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
