86-DOS, originally QDOS (Quick and Dirty Operating System) was the first DOS operating system. Developed by Seattle Computer Products, it was the basis of MS-DOS 1.0 and PC DOS 1.0.

History

Tim Paterson developed an operating system for Seattle Computer Products based heavily on CP/M. The company released two versions of QDOS in July and August 1980. The latter was followed up by a version named 86-DOS, which was also released in August 1980.

It was then licensed by Microsoft. Seattle Computer Products developed twelve versions of Q-DOS that were licensed by Microsoft and sublicensed to IBM through Microsoft from November 15, 1980, to May 12, 1981.

Microsoft then purchased Q-DOS. Version 1.10 was released on July 21, 1981. Microsoft licensed 86-DOS 1.01 to IBM, which released it as PC DOS 1.0 on August 12, 1981.

Seattle Computer Products released one last version, 1.14, in the fourth quarter of 1981.

Revisions after this period were under the PC DOS and MS-DOS brand names.
