Steve Wozniak invented the first personal computer.
The personal computer (PC), which is also called the microcomputer and was designed for use by one person, was first developed for businesses in the early 1970s. Digital Equipment Corporation made the PDP8 for scientific laboratories. Steve Wozniak (1950– ) and Steve Jobs (1955– ), college dropouts who founded Apple Computer in 1976, are credited with inventing the first computer for home use. Working out of a garage, they spent six months developing the prototype (initial model) for Apple I. It was bought by some 600 hobbyists, who had to know how to wire, program, and set up the machine. Apple II was introduced in 1977 as the first fully assembled, programmable microcomputer. Nevertheless this machine still required customers to use their televisions as screens and to use audio cassettes for data storage. The Apple II sold for just under $1,300. That same year Commodore and Tandy introduced affordable personal computers. In 1984, Apple Computer introduced the Macintosh (Mac), which became the first widely used computer with a graphical user interface (GUI). By 1981, IBM (International Business Machines) had introduced a PC that quickly over-took the Mac.
