According to Atari co-founder Nolan Bushnell, Atari offered $100 () for each chip that was eliminated in the machine. Jobs had little knowledge of circuit board design and made a deal with Wozniak to split the fee evenly between them if Wozniak could minimize the number of chips. Wozniak reduced the number of chips by 50, by using RAM for the brick representation. The fact that this prototype had no scoring or coin mechanisms meant Woz's prototype could not be used. Jobs was paid the full bonus regardless. Jobs told Wozniak that Atari gave them only $700 and that Wozniak's share was thus $350 (). Wozniak did not learn about the actual $5,000 bonus () until ten years later. While dismayed, he said that if Jobs had told him about it and had said he needed the money, Wozniak would have given it to him. In 1975, Wozniak began designing and developing the computer that would eventually make him famous, the Apple I. With the Apple I, Wozniak was largely working to impress other members of the Palo Alto-based Homebrew Computer Club, a local group of electronics hobbyists interested in computing. The club was one of several key centers which established the home hobbyist era, essentially creating the microcomputer industry over the next few decades. Unlike other custom Homebrew designs, the Apple had an easy-to-achieve video capability that drew a crowd when it was unveiled. Apple formation and success By March 1, 1976, Wozniak completed the basic design of the Apple I computer. He alone designed the hardware, circuit board designs, and operating system for the computer. Wozniak originally offered the design to HP while working there, but was denied by the company on five occasions. Jobs then advised Wozniak to start a business of their own to build and sell bare printed circuit boards of the Apple I. Wozniak, at first skeptical, was later convinced by Jobs that even if they were not successful they could at least say to their grandchildren that they had had their own company. To raise the money they needed to build the first batch of the circuit boards, Wozniak sold his HP scientific calculator while Jobs sold his Volkswagen van. On April 1, 1976, Jobs and Wozniak formed the Apple Computer Company (now called Apple Inc.) along with administrative supervisor Ronald Wayne, whose participation in the new venture was short-lived. The two decided
