Well the easiest way without any hardware would be to play it into the cassette port from a WAV file

I don't know myself how people did it in the day. IIRC I think I read that Nine Tiles, who did Sinclair's software development, had some sort of emulator running on a minicomputer. There wasn't much of a commercial scene for the '81 and other than Sinclair themselves it was pretty much a cottage industry so they would've used their own proprietary solutions I would guess. For instance you could burn code onto EPROMS, or map some kind of interface into the spare memory map, that sort of thing.

Wouldn't be surprised if some of the few were doing the same as me, saving onto cassette and hoping for the best. With the exception of the legendary 3D Monster Maze, even the few 3rd Party commercial programs were pretty, um, basic.
