Abstract:
In this paper we examine the development of the micro-computer market in the early 1980's. CP/M, a widely adopted operating system, was orphaned by the user and development communities. A new operating system, DOS, and a new hardware platform, the IBM PC, became the prediminant industry standards. We examine the statistical relationship between data that reflects sales activity associated with hardware, software, and peripheral equipment for the competing platforms. We conclude that the economic process underlying the development of DOS differed from those underlying CP/M and that many of these differences related to the role of software development.
