The Atari Microsoft BASIC and Atari Microsoft BASIC II variants of the BASIC programming language were ROM cartridge or floppy disk packaged versions of the Microsoft BASIC dialect ported to the Atari 8-bit machines. The first version, released 1981, required 32 kB of RAM and was supplied only on floppy disk. The second version, released the next year, had most of the code on a ROM cartridge with additional functions on an optional floppy.
