“Thirty years ago, on July 27 1981, Microsoft bought the rights for QDOS (Quick and Dirty Operating System) from Seattle Computer Products (SCP) for $25,000. QDOS, otherwise known as 86-DOS, was designed by SCP to run on the Intel 8086 processor, and was originally thrown together in just two months for a 0.1 release in 1980 (thus the name).
Meanwhile, IBM had planned on powering its first Personal Computer with CP/M-86, which had been the standard OS for Intel 8086 and 8080 architectures at the time, but a deal could not be struck with CP/M’s developer, Digital Research.
IBM then approached Microsoft, which already had a few of years of experience under its belt with M-DOS, BASIC, and other important tools — and as you can probably tell from the landscape of the computer world today, the IBM/Microsoft partnership worked out rather well.”
An anonymous read over at Slashdot posted the above paragraph. It’s pretty close to how I remember things, it’s hard to believe all that was 30 years ago. Anyone else out there remember CP/M? Bonus points if you know what a PDP-1o was.
