While still with HP, Wozniak describes his moonlighting development, with Jobs, of the prototype of the arcade game Breakout for Atari, Inc in only four days. He also describes, without bitterness, how Jobs shortchanged him on the job. Jobs, who worked for Atari Inc., said he would give Wozniak half of "whatever they paid him" for development of the game. Jobs subsequently gave Wozniak $375, saying Atari Inc. paid him $750 for the game. Later Wozniak found out that Atari Inc. actually paid Jobs five thousand dollars for the game.
