If you restrict yourself to programs that don't need an OS or hardware, you're going to be looking at a pretty small set of programs.

I don't, but I do restrict that you run it on the same OS as it was designed for.
Backwards-compatibility in OSes is the exception, not the rule. IBM does pretty well here. Microsoft does okay. Linux is either fine or a disaster depending on who you ask. MacOS, iOS, and Android laugh at the idea. And even the OSes most dedicated to compatibility devote a ton of effort to ensuring it on new hardware.
