During the 1970s, Gary Kildall created the CP/M operating system among other operating systems and programming tools, and subsequently founded Digital Research, Inc. (or "DRI") to market and sell his software products. Kildall was among the earliest individuals to recognize microprocessors as fully capable computers (rather than simply as equipment controllers) and to organize a company around this concept. At the same time, IBM was developing its personal computer project and was looking for someone who could develop an operating system for the PC. Gary Kildell had exactly what IBM wanted, but then due to some misunderstandings, the project went to Microsoft. Microsoft licensed the PC OS called DOS from another company Seatlle computers and charged IBM a bomb for it. This is the story of how Gary Kildell who could have been the man who build DOS and his company Digital Research could have been what Microsoft is.
