Cheering fans at an Oakland A's game. The team scores a run. The Golden State Warriors play a game. The Oakland Raiders celebrate a victory. Children play a football game. Clips from Rocky, Star Wars, Saturday Night Fever. Couples dance in a competition. People having fun at a roller rink. Two men push a car into a parking lot. A sign apologizing for the gas shortage. A man talks about the gas shortage. A man pumps gas as the numbers on the meter tick up. Cars on the road in San Francisco. An aerial view of Silicon Valley. Two little girls walk through a field of flowers in the South Bay. Computer chips being manufactured and put to use. A Porsche with a "WOZ" vanity plate pulls into a driveway. Steve Wozniak, seated in front of two computers, gives an interview.
