September Tim Patterson shows Microsoft his 86-DOS, written for the 8086 chip. EDLIN was supposed to last only six months, before being replaced. A week later, the EDLIN lineĮditor was created. It had been created in only two man-months, the DOS worked surprisingly well. Sufficiently different from CP/M to be considered legal. Although it was completed in a mere six weeks, QDOS was Paterson'sĭOS 1.0 was approximately 4000 lines of assembler source. August QDOS 0.10 (Quick and Dirty Operating System) is shipped by Seattle Computer Products. CP/M (Control Program for Microcomputers) was written by Gary Kildall ofĭigital Research several years earlier and was the first operating system for microcomputers in general use. QDOS had been developedĪs a clone of the CP/M eight-bit operating system in order to provide compatibility with the popular business applications System (DOS), due to delays by Digital Research in releasing a CP/M-86 operating system. Seattle Computer Products decides to make their own disk operating April Tim Patterson begins writing an operating system for use with Seattle Computer Products' 8086-basedĬomputer (for the new Intel 16-bit 8086 CPU). February Apple Computer releases DOS 3.2. He calls it CP/M (Control Program/Monitor). DOS history outlineĪ simple operating system in his PL/M language.

OS, actually a program loader and a couple of dozens of utilities. It was the real revolution in programming despite the fact that DOS was a pretty primitive But PC revolution was a unique period that There have always been a gifted young programmers, and there always will be. I am writing this page about semi-forgotten, short but very influential epoch in programming.
