MS-DOS is 30 years old today. Well, kind of. On 27 July 1981, Microsoft gave the name MS-DOS to the disk operating system it acquired on that day from Seattle Computer Products (SCP), a hardware company owned and run by a fellow called Rod Brock.<\/p>\n
SCP developed what it at various times called QDOS and 86-DOS to run on a CPU card it had built based on Intel’s 8086 processor.<\/p>\n
The company had planned to use Digital Research’s CP\/M-86 operating system, then still in development. But, having released the card in November 1979 – it shipped with an 8086-compatible version Microsoft’s Basic language interpreter-cum-operating system – and reached April 1980 without CP\/M-86 becoming available to bundle, SCP decided it had to create its own OS for the card.<\/p>\n
Enter, in August 1980, QDOS. It really did stand for Quick and Dirty Operating System. That’s actually what it was: a basic but serviceable OS good for coding and running programs written in 8086 assembly language – the x86 instruction set. It was written by SCP’s Tim Paterson, who had joined the company as a programmer a couple of years previously and began work on it in April 1980.<\/p>\n
