Alcorn recalled that he originally used a chip from Fairchild to generate the display for the score, but it cost $5, and he could do the same thing for $3 using TTL parts, though the score was cruder. Thus, the ball would move in relation to the screen, both vertically and horizontally, just as a misadjusted television picture may roll. We did it with about 10 off-the-shelf TTL parts by making sync generators that were set one or two lines per frame off register.вЂќ вЂњWe were faced with having a ball move into any of the spots in a 200-by-200 array without being able to store a move. вЂњThere was no real bulk memory available in 1972,вЂќ he said. Alcorn was trying to get the price down into the range of an average consumer product, which took a lot of ingenuity and some tradeoffs. Alcorn could not read his schematics and had to redesign it. Bushnell had developed the motion circuit in his attempt to make the Computer Space terminals smarter, but Mr. Bushnell to consider designing it as a real game-and that is why it was a success. Pong, on the other hand, was too simple for an EE like Mr. The ice water thawed in my veins.вЂќД¬omputer Space appealed only to sophisticated game players-those who were familiar with space games on mainframe computers, or those who frequent the arcades today.

Bushnell said, вЂњThe economics were not longer a $6000 computer plus all the hardware in the monitors they became a $400 computer hooked up to a $100 monitor and put in a $100 cabinet.

Alcorn said, adding, вЂњWe would have been bankrupt if she had.вЂќ вЂњHe actually had the order for the computers completed, but his wife forgot to mail it,вЂќ Mr. Bushnell said, he realized he did not need the central computer at all-the terminals could stand alone.

Bushnell began trying to take the load off the central computer by making the terminals smarter, adding a sync generator in each, then circuits to display a star field, until the computer did nothing but keep track of where the player was. He began designing a space game to run on such a timeshared system, but because game action occurs in real time, the computer was too slow. Then in 1971 he saw a Data General computer advertised for $5000 and determined that a computer game played on six terminals hooked up to that computer could be profitable. He divided the cost of a computer by the amount of money an average arcade game made and promptly dropped the idea, because the economics did not make sense. Bushnell had worked at an amusement park and had also played space games on a PDP-10 at college.
