In 1969, after graduating from college, Nolan Bushnell worked as an engineer in California for Ampex, an electronics company that worked in audio and video recording technology. While at a club for playing Go, he met researcher Jim Stein, who worked for Stanford University's Stanford Artificial Intelligence Project; Bushnell learned from him that "Spacewar!" was running on the laboratory's PDP-6, and played the game against him there when visiting. Bushnell had previously worked during the summer at Lagoon Amusement Park in Utah as a manager of the games department overseeing the arcade games, and when he saw "Spacewar!" he believed that an arcade game version of the game would be very popular. The high price of computers capable of running the game, however, meant that any such arcade game would not be economically feasible. In the spring of 1970, however, he saw an ad for the Data General Nova computer, which cost only , and thought again about his "Spacewar!" arcade game idea. He believed that at that price the game would be economically viable if he were able to connect four monitors and coin slots to allow multiple games to run simultaneously. He showed his office mate and fellow Ampex engineer Ted Dabney "Spacewar!" at the Stanford laboratory, and the two agreed to work together to try and design a prototype of the game. Bushnell had some experience with computers and digital engineering but not enough to create the game on his own, while the older Dabney was more experienced with analog and hardware engineering, as he had designed video processing and control circuits and power supplies.
