The IBM PC and MS-DOS, the iconic duo of the early 80s. The two are so interconnected that it's hard to mention one without the other. But in 1980 DOS wasn't IBM's first choice for their soon-to-be flagship hardware. IBM had wanted to license Gary Kildall's CP/M, but in a strange series of events the deal fell through. Legend states that Kildall lost the contract b was too busy flying his private plane to talk business with IBM, but is that true? Today we look at the development of CP/M, why it was a big deal, and why the PC ultimately shipped with Microsoft software.
