Nutting Associates redesigned version of the device called "Computer Quiz" (1967) created by Richard Ball of Marketing Services. In 1968 the model was redesigned into a solid-state version. In 1971, Nolan Bushnell sold Nutting Associates on manufacturing the game "Computer Space" (1971). About 1,500 units were manufactured. Afterwards, Bushnell wanted a large ownership stake in the company to continue creating games for Nutting Associates, but left after not being given that opportunity to form Atari Inc. with Ted Dabney. Nutting Associates continued manufacturing video games up until 1977 when the company was sold to "Si" Redd. A new Nutting Associates company was
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.
