<P> Production was discontinued on September 30, 1977, after the June 10, 1977, introduction of its successor, the Apple II, which Byte magazine referred to as part of the "1977 Trinity" of personal computing (along with the PET 2001 and the TRS - 80). </P> <P> On March 5, 1975, Steve Wozniak attended the first meeting of the Homebrew Computer Club in Gordon French's garage . He was so inspired that he immediately set to work on what would become the Apple I computer . After building it for himself and showing it at the Club, he and Steve Jobs gave out schematics (technical designs) for the computer to interested club members and even helped some of them build and test out copies . Then, Steve Jobs suggested that they design and sell a single etched and silkscreened circuit board--just the bare board, no electronic parts--that people could use to build the computers . Wozniak calculated that having the board design laid out would cost $1,000 </P> <P> The Apple I went on sale in July 1976 at a price of US $666.66, because Wozniak "liked repeating digits" and because of a one - third markup on the $500 wholesale price . </P> <P> The first unit produced was used in a high school math class, and donated to Liza Loop's public access computer center . About 200 units were produced and all but 25 were sold during nine or ten months . </P>
