Atari DOS

Atari DOS, (often just known as DOS), was the disk operating system used with the Atari 8-bit family of computers.Getting the Atari computer to access a disk drive required operating system extensions to be loaded into the computer. These extensions to the operating system added the disk handler and other file management features.The most important extension was the disk handler. In Atari DOS 2.0, this was the File Management System, or FMS. The FMS was an implementation of a File system that loaded from a floppy disk. This meant additional memory was needed to run with DOS loaded, at least 32K RAM.
