I have an itty-bitty (3K) integer basic for the 8080 which I wrote way back in
the 70's. You can get it up and running pretty easily and it doesn't depend on
any special I/O ... Source is included on my Altair disks, which you can access
under my simulator (you can also run the BASIC to try it out if you like).
I have a number of other 8080 code bits which you might find useful - editor,
assembler, disassembler, debugger, games etc. much of which is also available
in my Altair disks.
