This is some random old software that should install and run in
Windows, DOS, Linux, and/or Wine. Some is abandonware, some is
freeware/FOSS, and some is of questionable legality.

I still have a bunch of stuff on external drives that I got from
archive.org, and various warez sources in the late 90s/early 00s.
I don't have the ambition to paw through that stuff at the moment,
especially since most of it is Windows software whose role is now
better filled these days by Linux software.
