FL> The fact that so many people still remember these thigs is kinda scary... you always remember your first geek love! :) you have to understand the vt100 phenomenon. not far before there were no cheap crt terminals. they all were printer types (teletypes and others) or fancy systems. dec came out with the vt52 which had the keyboard and crt in one box but the key was addressable cursor stuff. the vt100 added more cursor features, room for expansion slots AND a detached keyboard! this was a major leap forward and dec sold countless of them and it spawned a large vt100 compatible industry. the current xterm and many other teminal emulators all have vt100 modes as it was among the first entries in termcap (and in many apps that hardwired vt100 codes). the expansion slot section could even take an LSI-11 board and the cabinet could handle a pair of dectape drives (the small qic type) so you could have a fully booting computer running rt-11 inside the terminal! as i said, i (like many others here) worked and played with vt100s for many years. uri -- Uri Guttman ------ [EMAIL PROTECTED] -------- http://www.stemsystems.com --Perl Consulting, Stem Development, Systems Architecture, Design and Coding- Search or Offer Perl Jobs ---------------------------- http://jobs.perl.org _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
