What does "oldest" OS even mean? I haven't used TSOS/BS2000 but its Wikipedia article suggests that while the OS lineage dates back to 1968 that anyone using it currently is using some currently maintained developed version of it.
In my mind supporting an old OS means e.g. that someone is still running old terminals that still run actual Windows 95 (emulator or not), DOS etc.
It wouldn't be meaningful to say "this runs on an OS from the mid-80s!". Only to find that it's all C# code targeting last year's release of Microsoft Windows (which has its eventual origins in the mid-80s).
- abrax3141 5y agoWell, the exact same built-in text editor, called EDT, and he exact same basic command language (like what is "ls" in unix is "fstat" in TSOS) is still nearly exactly the same as I remember it from the 70's. (Of course, there have been improvements and additions, like, say, the internet! .... although, actually, we were on the early internet (arpanet) then too! In fact, my summer job just before college was tinning wires that did the local arpanet interconnect! :-)
