Steve Jobs by Walter Isaacson Read Free Book Online

when I was in second grade, not by equations but by having me picture it.”
    Woz’s father taught him something else that became ingrained in his childlike, socially awkward personality: Never lie. “My dad believed in honesty. Extreme honesty. That’s the biggest thing he taught me. I never lie, even to this day.” (The only partial exception was in the service of a good practical joke.) In addition, he imbued his son with an aversion to extreme ambition, which set Woz apart from Jobs. At an Apple product launch event in 2010, forty years after they met, Woz reflected on their differences. “My father told me, ‘You always want to be in the middle,’” he said. “I didn’t want to be up with the high-level people like Steve. My dad was an engineer, and that’s what I wanted to be. I was way too shy ever to be a business leader like Steve.”
    By fourth grade Wozniak became, as he put it, one of the “electronics kids.” He had an easier time making eye contact with a transistor than with a girl, and he developed the chunky and stooped look of a guy who spends most of his time hunched over circuit boards. At the same age when Jobs was puzzling over a carbon microphone thathis dad couldn’t explain, Wozniak was using transistors to build an intercom system featuring amplifiers, relays, lights, and buzzers that connected the kids’ bedrooms of six houses in the neighborhood. And at an age when Jobs was building Heathkits, Wozniak was assembling a transmitter and receiver from Hallicrafters, the most sophisticated radios available.
    Woz spent a lot of time at home reading his father’s electronics journals, and he became enthralled by stories about new computers, such as the powerful ENIAC. Because Boolean algebra came naturally to him, he marveled at how simple, rather than complex, the computers were. In eighth grade he built a calculator that included one hundred transistors, two hundred diodes, and two hundred resistors on ten circuit boards. It won top prize in a local contest run by the Air Force, even though the competitors included students through twelfth grade.
    Woz became more of a loner when the boys his age began going out with girls and partying, endeavors that he found far more complex than designing circuits. “Where before I was popular and riding bikes and everything, suddenly I was socially shut out,” he recalled. “It seemed like nobody spoke to me for the longest time.” He found an outlet by playing juvenile pranks. In twelfth grade he built an electronic metronome—one of those tick-tick-tick devices that keep time in music class—and realized it sounded like a bomb. So he took the labels off some big batteries, taped them together, and put it in a school locker; he rigged it to start ticking faster when the locker opened. Later that day he got called to the principal’s office. He thought it was because he had won, yet again, the school’s top math prize. Instead he was confronted by the police. The principal had been summoned when the device was found, bravely ran onto the football field clutching it to his chest, and pulled the wires off. Woz tried and failed to suppress his laughter. He actually got sent to the juvenile detention center, where he spent the night. It was a memorable experience. He taught the other prisoners how to disconnect the wires leading to the ceiling fans and connect them to the bars so people got shocked when touching them.
    Getting shocked was a badge of honor for Woz. He prided himself on being a hardware engineer, which meant that random shockswere routine. He once devised a roulette game where four people put their thumbs in a slot; when the ball landed, one would get shocked. “Hardware guys will play this game, but software guys are too chicken,” he noted.
    During his senior year he got a part-time job at Sylvania and had the chance to work on a computer for the first time. He learned FORTRAN from a book and read the manuals for most of the
