DOS XL is a discontinued disk operating system for Atari 8-bit computers, written by Paul Laughton, Mark Rose, Bill Wilkinson, and Mike Peters and published by Optimized Systems Software, known as OSS. It was engineered to remain compatible with Atari DOS, which had been created by the same team of developers before they left Atari to found OSS. DOS XL reached its final release, version 2.30, in 1984, and was distributed under a proprietary license for the Atari 8-bit computer line. As a product built by Atari DOS's own original authors, it represented a commercially available continuation and improvement of Atari's stock disk operating system rather than an unrelated clone.
