"Computer Space" debuted at the MOA show on October 15–17, 1971. Dabney's wooden cabinet for the initial prototype was replaced with a curvy, futuristic fiberglass cabinet designed by Bushnell with modelling clay and built by a swimming pool manufacturer. A control panel extended from the main body of the cabinet and contained the four control buttons; Syzygy had hoped to use a joystick to control the rocket's movement, but found that it broke too easily, failing to last a single night in a location test. The "Galaxy Game" designers had run into the same issue, but had solved it with expensive customized military surplus joysticks. The cabinet displayed the Nutting Associates name and logo, along with the term "Syzygy engineered". Nutting displayed four cabinets at the MOA show, one each in red, blue, white, and yellow, with the implication that the game was already in production, though they were in fact the only four cabinets then produced. These initial cabinets were in solid colors, though later ones would use a sparkle finish. The cabinets were damaged during transport, and one monitor was broken; Syzygy repaired the three working cabinets and opened up the fourth to demonstrate the internals to attendees. The game was popular with viewers, with a crowded display area, and trade magazine "Cash Box" called it "very promising" and "very glamorous". Game distributors, however, were hesitant about the game, with concerns raised about the game's potential, reliability, and the embedded monitor's attractiveness to thieves; recollections are mixed as to whether Nutting took a handful of orders or none at the show. Nutting ordered a large production run regardless, on the expectation that the distributors would come around with further exposure. The game entered initial production sometime in November or December, and began full production around the end of January 1972.
