Nutting Associates was an arcade game manufacturer from Mountain View, California, formed in 1965 when Bill Nutting spun off "The Knowledge Computer" prototype from Edex Corp. Nutting, Richard Ball, and an electronic technician redesigned it to "The Computer Quiz" coin-operated trivia game. It underwent two redesigns, the third being the first solid state plug-in coin-op game. Ball did a concept, design and marketing brief for a coin-op video game. He started to develop "Space Command" but left Nutting to develop Cointronics Corp. with co-worker Ransom White. Their game "Lunar Lander" was the first audio reward game that in 1969 used the NASA tape "The Eagle has landed," as the reward.
