ABSTRACT
Before personal computers, the technological world operated on mainframe computers. Harvard University researcher Howard Aiken developed the first mainframe computer in 1936. It was called the Harvard Mark I and “was not ready for use until 1943. Steve Jobs was responsible for the marketing and sales of the computers and approximately 200 units were produced—with the majority sold during a span of 9 or 10 months. Wozniak’s work on the Apple II pioneered new industry standards for microcomputers, most notably the inclusion of its 50-pin expansion slots that allowed users to expand the functionality of the base motherboard. An article by Compute! magazine explained that “home computers” had developed a connotation of being low-end machines primarily used for playing video games. Apple’s John Sculley flat out denied that his company was selling “home computers,” instead referring to them as “computers for use in the home”.
