If you fancy a modern take on this environment, RISC OS Pico is the 32-bit ARM version of BBC BASIC on top of the 32-bit ARM version of Acorn MOS:

Same language, editor, commands, etc. but about 2000x faster.

Runs great on a Raspberry Pi Zero, which is $5 and accepts USB peripherals & an HDMI screen.

The same code will work but without fighting the weird restrictions of early-1980s hardware. (Even when emulated.)
