Basically the title

    • …I still have some OS/2 (or, rather, ArcaOS) systems running here.

      Mostly for a very limited subset of things that never really migrated across to “modern” windows - I have a BBS running on there because 16 bit DOS apps on OS/2 was pretty much the best way to run them when it was 1994, and in 2024 it’s still the best way to deal with them.
