Nolan Bushnell in 1975. Using borrowed parts from Atari, having the main PCB printed up by Atari employee Howard Cantin, and receiving further assistance from Atari employee Ron Wayne, two non-employees, Steve Jobs and Steve Wozniak—both of whom had previously been involved in the development of the Atari arcade game "Breakout"—created and marketed their own home computer. They offered the design to Bushnell, but Atari had no desire to build computers at the time, instead focusing on the arcade and home console markets. In 1976, Steve Jobs went to Nolan to get him to put in some money in exchange for a
Nolan Bushnell restaurant executive and focused on Catalyst Technologies. Through 1981 and 1982, Bushnell concentrated on PTT subsidiaries Sente Technologies and Kadabrascope. Sente was a reentry into the coin-operated game business. Arcade cabinets would have a proprietary system and a cartridge slot developed by Data East Corporation, so operators could refresh their games without having to buy whole new cabinets. Kadabrascope was an early attempt at computer assisted animation. In 1983 as the restaurants started to lose money, Sente, though profitable, was sold to Bally for $3.9 million and Kadabrascope was sold to Lucas which became the beginnings of what became Pixar.
