MS-Dos Turns 30 !!!

by Ankit on August 1, 2011

Last week it was the birthday of MS DOS and it has turned 30 now! So, today I am gonna share the story behind this prodigious OS. In fact I would go one step further and say that it was only because of it Microsoft became one of the big guns in personal computing and its founders some of the richest men on the planet. Actually MS Dos was the first operating system that Microsoft launched with the IBM PC, that they sold during the initial days.

Thirty years ago on 27-July-1981 Microsoft finalized a deal with Seattle Computers to purchase their operating system which was then called QDOS (Quick and Dirty Operating System). This OS was designed by an employee named Tim Paterson of Seattle Computers. It is quiet intesting to know that Tim designed this OS (QDOS) in just 6 weeks for some in house hardware!

MS DOS Turn 30

Microsoft bought all the rights to QDOS for a sum of $50,000. After QDOS was purchased by Microsoft they renamed it to MS-DOS (Microsoft Disk Operating System) and then they bundled it with the IBM pc. It is said that Microsoft kept there deal with IBM a secret from Tim Paterson and his company, Seattle Computer Products. If Seattle Computers would have been aware about such a big deal they would have sealed a deal with IBM themselves and then Microsoft would not have been what it is today.

Later Microsoft offered a job to Tim Paterson and Tim worked with Microsoft until 1998. After the year 1998, Tim Paterson started his own company Paterson Technology. Paterson technology is a small company that develops unique hardware and software products near Seattle, Washington.

MS DOS was updated many times uptill 1994 before it was finally replaced by Windows 95. And now it is almost dead and Microsoft is not induged in doing any further developments in the OS.
