Not sure why you would be having problems. For me, all my old stuff
just works in that environment - and I'm talking about stuff from that
era as well - Borland Turbo Pascal 3 compiler, my old DOS command-line
utilities and games, etc. If it still ran in a command prompt in XP,
it still runs in XP Mode. Sometimes you have to tweak the settings,
make sure paths are correct, etc., but they run...

I've long since replaced the few things that wouldn't work in a command
prompt so I don't have much need for pure native environments like that
for anything other than XP, and that only for the 16-bit stuff. I've
yet to find a 32-bit program that has a problem in 64-bit. I'm sure
they are out there, but I don't use any of them.

I still have all the original install media from every OS I've ever run
as well. I go all the way back to DOS 3 myself, though I had bootleg
copies of DOS 2 that I played with at the time. Never saw any reason
to use the older versions in preference to the newer versions though.
Not sure why I keep all of them, but I'm a pack rat that way.
