In 1975, the two Steves started attending meetings of the Homebrew Computer Club. New microcomputers such as the Altair 8800 and the IMSAI inspired Wozniak to build a microprocessor into his video terminal 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.
