 They had soon discovered that while a general-purpose computer cheap enough for an arcade game would not be powerful enough to run enough games of "Spacewar" to be profitable, a computer purpose-built for solely running one game could be made for as low as US$100.By August 1971 when Bushnell called Tuck and Pitts, he and Dabney had already displayed a prototype of their "Computer Space" game in a bar near Stanford and had found a commercial manufacturer for the game in Nutting Associates.They were curious about what Tuck and Pitts had done to make a commercially competitive version of the game, but were relieved, though also somewhat disappointed, to find that they had not solved that problem yet.
