You might have a lot of fun with DOS, if you wanted physical hardware look for a 486 cpu with 8 or so megs of ram, you can put on DOS6.11 and Windows 3.11 and have a play, this was (close enough)the final step before Windows 95
Also have a look at installing djgpp and you can see what a DOS based text-ui IDE looked like.
Also install Desqview for what an alternate desktop environment looks like.
One thing you’ll learn is that installation of all of this will require some tweaking and research, you’ll have to learn about config.sys and playing with extended memory managers, but that’s part of the fun!
Might be more fun to do this on an emulator though, because otherwise you’ll have to mess about with floppy disks or maybe early CDROMs and getting hold of functional ones might be challenging.
That era had tons of great games too! Duke Nukem 1 and 2, Blake Stone, Nyet, Jill of the Jungle, DOOM, try a few games too
Have fun! Shout out if you get stuck!
