PC DOS version 1.0, which supported only floppy disks, was shipped when IBM first released their PC in August 1981. They too outsourced it, by first licensing then purchasing an operating system from Seattle Computer Products variously called QDOS (Quick and Dirty Operating System”) and 86-DOS. When Microsoft signed the contract with IBM in November 1980, they had no such operating system. But their favored OS was the newly-written PC DOS, commissioned by IBM from the five-year-old Seattle-based software company Microsoft. Although IBM had prodigious internal software development resources, for the new PC they supported only operating systems that they did not themselves write, like CP/M-86 from Digital Research in Pacific Grove CA, and the Pascal-based P-System from the University of California in San Diego. This “outsourcing” attitude extended to the software as well. That included adopting the Intel 8088 microprocessor as the heart of the computer.
