What is the relationship of qdos to cp m and ms dos?
CP/M came out first for the 8080 and was offered to Intel, they rejected it as not necessary. The author Gary Killdell sold it himself and developed versions for other microprocessors. When IBM decided to do the PC they chose CP/M-86 as the operating system. But for unclear reasons Gary would not sign their NDA. IBM could not proceed, but Microsoft had already signed an NDA to provide their BASIC for the PC. IBM turned to them, however Microsoft had no operating system of their own to offer. They found and bought out the developer of QDOS (quick and dirty OS) a CP/M-86 clone. With minor modifications it became the first version of both MSDOS and PCDOS.
