Teaser quote:
"He [Steve Wozniak] introduced all of us to his demonstration about his Apple -- what would become the Apple I. I saw his demonstration and I go, 'Oh, that is very cool.'"
"I had what I used to call the bash and bang test. I'd load up the program on an Atari 800 or 1200 or whatever I happend to have at the time, and as the program was running I would just start pounding on the keys at random, just taking my fists and just banging on the keyboard."
