You can run Windows XP in a virtual machine quite easily to run old software. I have a licensed version of Windows XP installed in a virtual machine. And I have old computers that still have Windows XP... because I never throw any computer hardware out. I have what is basically a museum.
But using Windows XP is a bit of a frustrating experience because you, like me have probably gotten used to some of the niceties that later versions of Windows provide.
You got any CP/M computers? I keep one in the closet just in case. I think my father’s Commodore with cassette tape drive got trashed a few decades ago, however.
