Dennis Ritchie and Ken Thompson at a pretty well maxed out DEC PDP11 computer and two Teletype model 33 terminals.

    There were days I set my TERM=33 to get into "open mode" in real vi. Made very bad modem connections a bit more usabale. I picked it because it had the smallest entry in /etc/termcap.

    I never had sucess using VI with a TTY. I used to use 'ed'. Later on having access to DEC VT-100 CRT's I learned to use 'vi' and still use it today under Windows NT, 2000, XP and Unix/Linux...

    There was a company that made a great set of Unix tools for Windows 95,NT,2000,XP & DOS machines called Thompson Toolkit. It was at:


    Very small and compact. True too Unix. Not like that UWIN
    bloatware. TTK supported input/output redirection, pipes, Bourne shell scripts, AWK, grep, etc.

    Nah, Windows is not something I use regularly. I've got a linux box at work, a linux laptop at home, a netbsd shell account for my email. I still find myself using ed from time to time, mostly by accident. Try a "crontab -e" on a Solaris box before you've set $EDITOR.... But I know enough ed to be able to use it.
  • PanelSwitchman 6y

    Yea, yea, yea
    ed huh

    ed and sed has its uses just like grep.
    Which version of Linux do you find to be most compatable?
    My newest machine has USB KBD&Mouse and Linux does not seem to like them.
  • Elijah 6y

    I don't get religious about distros. I use both Ubuntu and SUSE currently. USB keyboards and mice haven't given me any problems.
  • PanelSwitchman 6y

    Well I guess I'll have to try Ubuntu.

    Historic image: where Unix and GNU/Linux revolution were born. But...Where are the monitors, the speakers for audio and the mouse??? :)))))))
  • PanelSwitchman 6y

    GNU/Linux was not born until years later.

    Monitors, Speakers, Mouse?? These are the early days. 110 Baud teletypes, upper case only black & white CRT terminals from manufacturers long forgotten.

    Ah, to sit back and wait for hours while you printed some long source code on a Teletype...

    This is a beautiful picture...
  • PanelSwitchman 4y

    Yes it is. A collectors edition in many ways.
