IBM first approached Microsoft about its upcoming IBM Personal Computer (IBM PC) in July 1980, shortly after Gates's mother began working on United Way's executive board with IBM CEO John Opel.[27] On August 12, 1981, after negotiations with Digital Research failed, IBM awarded a contract to Microsoft to provide a version of the CP/M operating system, which was set to be used in the IBM PC. For this deal, Microsoft purchased a CP/M clone called 86-DOS from Tim Paterson of Seattle Computer Products for less than US$100,000, which IBM renamed to IBM PC DOS. The original CP/M was made by Gary Kildall of Digital Research, Inc. Due to potential copyright infringement problems with CP/M, IBM marketed both CP/M and PC DOS for US$240 and US$40, respectively, with PC DOS eventually becoming the standard because of its lower price.[28][29] Thirty-five of the company's 100 employees worked on the IBM project for more than a year. When the IBM PC debuted, Microsoft was the only company that offered operating system, programming language, and application software for the new computer.[27] The IBM PC DOS is also known as MS-DOS.
In 1983, in collaboration with numerous companies, Microsoft created a home computer system, MSX, which contained its own version of the DOS operating system, called MSX-DOS; this became relatively popular in Japan, Europe and South America.[10][31][32] Later, the market saw a flood of IBM PC clones after Columbia Data Products successfully cloned the IBM BIOS, quickly followed by Eagle Computer and Compaq.[33][34][35][36] The deal with IBM allowed Microsoft to have control of its own QDOS derivative, MS-DOS, and through aggressive marketing of the operating system to manufacturers of IBM-PC clones Microsoft rose from a small player to one of the major software vendors in the home computer industry.[37] With the release of the Microsoft Mouse on May 2, 1983, Microsoft continued to expand its product line in other markets. This expansion included Microsoft Press, a book publishing division, on July 11 the same year, which debuted with two titles: Exploring the IBM PCjr Home Computer by Peter Norton, and The Apple Macintosh Book by Cary Lu.[7]
