Tried it on my kid's gaming PC just now. Windows 10 complains about it not being 64 bit.

Runs fine in DOSBox. Left it open, he'll be so excited when he gets home from school!

Runs on "today's" PC with a 32 bit Windows

Should run on a floppy with FreeDOS :-P

(AFAIK FreeDOS has better support for modern PCs than MS-DOS though you might find some that also boot MS-DOS)

64 bit Windows won't run 16 bit executables.

here you are : 16-bit Windows (Windows 1.x, 2.x, 3.0, 3.1, etc.) on 64-bit Windows

I imagine it would run OK in DOSBox.
