You people may think that MS-Dos (Microsoft Disk Operating System) was created by Microsoft Corporation!!! Hey that is not true!! It was created by Seattle Computer in November 1979 and it was known as QDOS, stood for Quick and Dirty Operating System. Unfortunately, it has lasted much longer than that as part MS-DOS. n the last few days of 1980, a new version of the DOS was released, now known as 86-DOS version 0.3. Seattle Computer passed this new version on to Microsoft, which had bought non-exclusive rights to market 86-DOS and had one customer for it at the time. In April 1981, Seattle Computer Products released 86-DOS version 1.00, which was very similar to the versions of MS-DOS that are widely distributed today. In July 1981, Microsoft bought all rights to the DOS from Seattle Computer, and the name MS-DOS was adopted.
