@thomasfuchs @ask I have used a basic on CP/M, on an Interact model J. Microsoft did not invent BASIC. BAS, Chipmonk, or YABASIC are among the viable options that might be leveraged. Microvideo 8k color basic (written for the 8080/Z80 cpus) might be an option for compatible platforms. Basic did exist before Microsoft did exist, so don't be limited by Microsoft.
