The Apple I was Steven Wozniak's first contribution to the personal computer field. It was designed over a period of years, and was only built in printed circuit-board form when Steve Jobs insisted it could be sold. It debuted in April 1976 at the Homebrew Computer Club in Palo Alto, but few took it seriously. The Apple I was based on the MOStek 6502 chip, whereas most other "kit" computers were built from the Intel 8080. The Apple I was sold through several small retailers, and included only the circuit board. A tape-interface was sold separately, but you had to build the case. The Apple I's initial cost was $666.66
