!Background
Atari licensed the the Microsoft "9k BASIC" for their new machines, intending to add a number of new commands to it to take advantage of the machine's graphics and sound capabilities. Unfortunately, they had designed the machines to allow only 8k in the ROM cartridges, and in spite of considerable effort, they were never able to get even the original version to fit, let alone any of the extensions. And thus [Atari BASIC], which was written to fit into 8k.
In 1981, Atari released their original extended version of Microsoft BASIC on disk. This version included the various extensions, and as a result was much larger than the cartridge version. It could only run on machines with at least 32k of RAM, and after loading it left little RAM free; on a 48k machine about 20k was left.
In spite of these limitations, MS BASIC had a number of advantages over Atari BASIC. For one, it supported all of the standard MS commands, making it much easier to port BASIC programs from other platforms to the Atari. It also included additional editing commands for renumbering, merging, and deleting blocks of lines. And most importantly, it was much faster; Atari BASIC had a number of well-known performance problems that MS BASIC did not, and this was enough to make most BASIC programs run much faster in MS BASIC.
The disk-based version was later replaced by [Microsoft Basic II], which used a ROM cartridge for the key parts of the language, and put extensions on a separate floppy disk.
