Apple Computer, Inc. ( NASDAQ: [http://quotes.nasdaq.com/asp/SummaryQuote.asp?symbol= }&selected= } }]) is a Silicon Valley company based in Cupertino, California, whose main business is computer technologies. Best known for its range of Macintosh computers and, more recently, its iPod personal audio ( MP3 and otherwise) player and iTunes Music Store, Apple has a reputation for innovation in the high tech industry.

1 Pre-foundation

Before he co-founded Apple, Steve Wozniak had always been an electronics hacker. By 1975 he was working at Hewlett-Packard and helping his friend Steve Jobs design video games for Atari. To get computer time, Wozniak had been buying computer time on a variety of minicomputers hosted by Call Computer, a timesharingFor Timesharing in real estate, see timeshare in computer, see time-sharing. firm run by Alex Kamradt. The computer terminals available at that time were primarily paper-based: thermal printers like the Texas InstrumentsTexas Instruments better known in the electronics industry as TI is a company based in Dallas, Texas, renowned for developing and commercializing semiconductor and computer technology. History of Texas Instruments Texas Instruments was founded by Cecil H. Silent 700 were the state of the art. Wozniak had seen a 1975 issue of Popular ElectronicsA magazine published in the United States from 1954 to 2003, by Gernsback Publications (headed by Hugo Gernsback, author and inventor, and publisher of numerous technical, science fiction, and pulp magazines). In its later years it was retitled to its nic magazine on how to build your own computer terminalA computer terminal is an electronic or electromechanical hardware device. It is used for entering data into, and displaying data from, a computer or a computing system. Historical Early terminals were Teletypes (TTYs), later ones use a Visual Display Uni. Using off-the-shelf parts, Wozniak designed the Computer Conversor, a 24-line by 40-column, uppercase-only video teletype that he could use to log on to the minicomputers at Call Computer. Alex Kamradt commissioned the design and sold a small number of them through his firm.

In 1975Events January January 1 Watergate scandal: John N. Mitchell, H. Haldeman, John D. Ehrlichman are found guilty of the Watergate cover-up and are sentenced to 30 months to 8 years in jail on February 21 January 5 The Tasman Bridge in Tasmania, Australia, i Wozniak started attending meetings of the Homebrew Computer Club. Learning about the new microcomputers such as the Altair 8800The MITS Altair 8800 is a microcomputer design from 1975, based on the Intel 8080A CPU. Sold as a kit through Popular Electronics magazine, the designers intended to sell only a few hundred to hobbyists, and were surprised when they sold over ten times th and the IMSAI , he realized he could build a microprocessor into his video teletype and have a complete computer.

At the time the only microcomputerGenerally, a microcomputer is a computer with a microprocessor (µP) as its CPU. Another general characteristic of these computers is that they occupy physically small amounts of space. Desktop computers, video game consoles, laptop computers, tablet PCs, CPUs generally available were the $179 Intel 8080, and the $170 Motorola 6800. Wozniak preferred the 6800, but both were out of his price range. So he watched, and learned, and designed computers on paper waiting for the day he could afford a CPU.

When MOS Technology released the famous 6502 in 1976 at $20, Wozniak immediately started writing a version of BASIC for the chip. After completion, he started designing a computer it would run on. The 6502 was designed by the same people who designed the 6800, as many in Silicon Valley left employers to form their own companies. Wozniak's earlier 6800 paper-computer needed only minor changes to run on the new chip.

Wozniak completed the machine and started taking it to Homebrew Computer Club meetings to show off the system. At the meeting, Wozniak met his old friend Jobs, who was interested in the commercial potential of the small hobby machines.
