86-DOS, known internally as QDOS for Quick and Dirty Operating System, is a discontinued operating system developed and marketed by Seattle Computer Products for its Intel 8086 based computer kit. It shared several commands with other operating systems such as OS/8 and CP/M, which made porting programs from CP/M easy since its application programming interface closely resembled that of CP/M. Microsoft licensed and then purchased the system and developed it further into MS-DOS and IBM PC DOS.

How did Microsoft come to own 86-DOS?
Microsoft licensed it in December 1980, then bought all rights in July 1981.
Microsoft first bought a non-exclusive license for 86-DOS from Seattle Computer Products in December 1980 for 25,000 US dollars. In July 1981, a month before the IBM Personal Computer was released, it bought all rights to the system for 50,000 US dollars. Microsoft then licensed 86-DOS to IBM, where it became PC DOS 1.0, and the license also let Microsoft sell DOS to other companies. Seattle Computer Products later claimed in court that Microsoft had hidden its relationship with IBM in order to buy the system cheaply, and it ultimately received a settlement of 1 million US dollars.
