Foundation to Apple

Steve Jobs and Steve Wozniak were outcasts while they were in high school; by 1975, they had withdrawn from Reed College and UC Berkeley, respectively. Wozniak designed a 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. Aside from their interest in up-to-date technology, the impetus for "the two Steves" seems to have had another source. In his essay From Satori to Silicon Valley (published 1986), cultural historian Theodore Roszak made the point that the Apple Computer emerged from within the West Coast counterculture and the need to produce print-outs, letter labels, and databases. Roszak offers a bit of background on the development of the two Steves’ prototype models.

In 1975, Wozniak started attending meetings of the Homebrew Computer Club. New microcomputers such as the Altair 8800 and the IMSAI inspired him to build a microprocessor into his video teletype and have a complete computer.

At the time the only microcomputer 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 its $20 6502 chip in 1976, Wozniak wrote a version of BASIC for it, then began to design a computer for it to 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 took it to Homebrew Computer Club meetings to show it off. At the meeting, Wozniak met his old friend Jobs, who was interested in the commercial potential of the small hobby machines.
