I've written an Intel 8080 emulator that was portable between Dec10/VAX/IBM VM CMS. That was easy - the 8080 can be done quite simply with a 256 value switch - I did mine in FORTRAN77.

Writing a BASIC interpreter, with floating point, is much harder. Gates, Allen and other collaborators BASIC was pretty damned good.

I still have a cassette tape with Microsoft Basic for the Interact computer. It's got an 8080.

You should upload the audio to the Internet Archive!

I remember my old Tandy Color Computer booting up and referencing Microsoft BASIC:

The computer came with some pretty good books with example BASIC programs to type in.

I have a MS Extended Basic cassette for the Sol-20, also 8080 based.
