Getting shocked was a badge of honor for Woz. He prided himself on being a hardware engineer, which meant that random shocks were 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 systems of the day, starting with the Digital Equipment PDP-8. Then he studied the specs for the latest microchips and tried to redesign the computers using these newer parts. The challenge he set himself was to replicate the design using the fewest components possible. Each night he would try to improve his drawing from the night before. By the end of his senior year, he had become a master. "I was now designing computers with half the number of chips the actual company had in their own design, but only on paper." He never told his friends. After all, most 17-year-olds were getting their kicks in other ways.
