There are several. If I remember correctly the story is featured in Woz’s book iWoz, but also in Job’s official biography. There is also a mention in the Wikipedia article of breakout: https://en.m.wikipedia.org/wiki/Breakout_(video_game)

I am sure there are many more sources out there.

Slightly clarification to OC’s remarks. The original contract was for $700 (so Jobs didn’t lie there). However, what Jobs kept secret is that there was a substantial bonus for reducing the amount of chips needed. Wozniak was specially good at optimizing the amount of chips in a circuit so the end design used substantially fewer chips and hence the bonus was much bigger than the amount agreed before.

Thanks for the clarification. Keep in mind too that the difference, $2150, would have been a _lot_ more money at the time. Roughly equivalent to $12k today if I can believe these sketchy-looking online inflation calculators.
