certificate is "Stephan Gary Wozniak", but his mother said that she intended it to be spelled "Stephen", which is what he uses. He has mentioned the surname “Wozniak” being Polish. In the early 1970s, Wozniak's blue box design earned him the nickname "Berkeley Blue" in the phreaking community. Wozniak has credited watching Star Trek and attending Star Trek conventions while in his youth as a source of inspiration for his starting Apple Computer. Career Pre-Apple In 1969, Wozniak returned to the San Francisco Bay Area after being expelled from the University of Colorado Boulder in his first year for hacking the university's computer system. He re-enrolled at De Anza College in Cupertino before transferring to the University of California, Berkeley, in 1971. In June of that year, for a self-taught engineering project, Wozniak designed and built his first computer with his friend Bill Fernandez. Predating useful microprocessors, screens, and keyboards, and using punch cards and only 20 TTL chips donated by an acquaintance, they named it "Cream Soda" after their favorite beverage. A newspaper reporter stepped on the power supply cable and blew up the computer, but it served Wozniak as "a good prelude to my thinking 5 years later with the Apple I and Apple II computers". Before focusing his attention on Apple, he was employed at Hewlett-Packard (HP), where he designed calculators. It was during this time that he dropped out of Berkeley and befriended Steve Jobs. Wozniak was introduced to Jobs by Fernandez, who attended Homestead High School with Jobs in 1971. Jobs and Wozniak became friends when Jobs worked for the summer at HP, where Wozniak, too, was employed, working on a mainframe computer. Their first business partnership began later that year when Wozniak read an article titled "Secrets of the Little Blue Box" from the October 1971 issue of Esquire, and started to build his own "blue boxes" that enabled one to make long-distance phone calls at no cost. Jobs, who handled the sales of the blue boxes, managed to sell some two hundred of them for $150 each, and split the profit with Wozniak. Jobs later told his biographer that if it had not been for Wozniak's blue boxes, "there wouldn't have been an Apple." In 1973, Jobs was working for arcade game company Atari, Inc. in Los Gatos, California. He was assigned to create a circuit board for the arcade video game Breakout.
