How cool is that:

  That's  the  first  time  I've  seen a such an old operating system in
  action.

  (A guy on reddit mentions that you don't need docker for this  because
  it's a PDP-11 emulator anyway. Full ack.)

  It's also not a complete system, it seems. C compiler doesn't work.

  Still, fun to play with. :-)
