      Mmm too modern for my tastes. Gotta go with the Lyons Electronic Office LEO I OS from 1951.

      It would need punch card malware lol.

      Ooh let’s go back even further to ENIAC in 1945.

        It’s nice you could just solder in new components.

        Tru64 and SunOS are furthest I go back I think, Commodore KERNAL/BASIC technically.

        Obscure OS you could actually run today could be Solaris…
