*The facts. According to Bill Johnson.American computer programmer Timothy Paterson, a developer for Seattle Computer Products, wrote the original operating system for the Intel Corporation’s 8086 microprocessor in 1980, initially calling it QDOS (Quick and Dirty Operating System), which was soon renamed 86-DOS. A year later, fledgling company Microsoft purchased exclusive rights to sell the system, renamed MS-DOS, to IBM for their newly developed IBM-PC. IBM-compatible versions were marketed as PC-DOS. Version 1.0 was released in 1981; additional upgraded versions kept pace with the rapidly evolving PC. Windows 95, introduced by Microsoft in 1995, incorporated MS-DOS 7.0 but ultimately superseded the MS-DOS platform. Starting with Windows NT, Microsoft’s operating systems were designed independently of MS-DOS, though they were capable of running some MS-DOS applications.*
Facts but missing lots of pivotal events. No mention of Gary Kildall. Windows 2.0 was a brief look at a Windows O/S. Windows 3.0 preceded WIN 95 as did Windows 3.1. Really who cares?
