Steve Wozniak1:22
Interesting. You're asking kind of a psychological question. What's your personality? And some of us grow up young and we get interested in science or math, whatever we're good at, that's what we value and think is important. And I was... I mean, I go back and I say, "Well, I kind of accidentally wound up in this area. I love interesting, unusual things." I could show you things right out of my pocket. And I just grew up being one of those people that... what's going on, interesting people, interesting movies, interesting stories. And I was very, very young, elementary school, 8 to 10 years old. And I was very good at electronics. My father was an electrical engineer and he got me interested and I loved it because it was close to math and I was the top math student in all my schools. So I was very good at electronics. In those days you'd buy a piece the size of a fingernail and it would have little colored icons around it. The colors told you what the value was and you knew the formulas for how electrons flowed through different kinds of materials, different kinds of devices. And I got a ham radio license when I was 10 years old. You bought a kit with 100 parts and you soldered them together and hooked them together and ran wires around dials and you could tune in radio frequencies on the receiver. Then I built a transmitter with hundreds of parts. I still think my parents thought it was incredibly expensive for what it was back then. But I got a ham radio license. You had to study a lot of the formulas of electronics and a lot of the rules of radio. We were the protectors of the radio waves, that was our theory. If there was an emergency in the world somewhere, you didn't have cell phones, you didn't have communication, even regular phones would usually be out. Ham radio operators sending messages from a country that was having a disaster for communication was very important. And I loved being in this area. Now, I got into science fairs. If you're in school, you have subjects that you learn, you take tests, and you do so well. But a science fair, you kind of come up with your own projects. And I went on a string from 8 years old, 9 years old, 10 years, I was going upwards as to what is the structure of the atom, what is an electron, how do electrons flow through water and devices like that. That was just my life because I was good at it. It had nothing to do with school. You didn't get a grade for it. You didn't get money. You didn't get recognition or anything. You just felt proud about doing it. By 8th grade, 12 years old, I built a project. I got the award for the best electronics project in the entire San Francisco Bay area, which includes Silicon Valley where I lived. I was competing with up to 12th graders and I was only in eighth grade and I was head of in electronics. Meanwhile, there was this digital side to the world that was the old analog world and it was a lot of mathematics and I loved it. I was an analog engineer first. They didn't have digital engineering as a course anywhere. You couldn't find a single book about what was in a computer. How do you make a computer? There were no books in bookstores, no magazines about computers. It was just an oddball word like space science, done in places like research and military. I stumbled on a journal. My father was an engineer at Lockheed. I stumbled on a journal in the hall closet. I started reading and it described ones and zeros that computers use and how their numbers are arranged and how you can add numbers in ones and zeros. I just sat down and practiced on paper. Then it had articles about logic, like philosophical logic statements with ANDs and ORs and inversion. Inversion means if you say true, inverted it's false. If you put false in, you get true out. Just reverses it. If it were light, it would be blue in is red out, red in is blue out. I learned about these things and I learned how to draw little symbols on a piece of paper that recognized logic. If this and this are both true, the output's true. If it's Wednesday and it's June, then the output is true. I loved practicing with that. I told myself this is going to be my passion for life. My thing in life is going to be this digital world. I was very young, 10 years old, and I just decided that was going to be it. Could I talk to a single person about it? No. Nothing like computer in school. No knowledge, no teachers, no friends, nothing of this. I became very shy. I had almost no friends anyway. Couldn't talk to almost anybody normally. But when I got home, I just loved playing with these little logic ideas on my science fair projects largely. Anyway, what is a computer came up to me one day. I didn't quite know how do you find out what a computer is? No books in bookstores. I was in high school and we didn't have a computer, but my electronics teacher arranged for me to go down once a week and program this thing called a computer, an IBM computer, at a company. I wrote my programs and got intrigued by doing that and how it worked. I saw a little book there, the Small Computer Handbook, and it described an early computer called the PDP-8 from Digital Equipment Corporation. I was intrigued by it. They let me keep the manual. I got to take it home. Inside the manual, it told me the architecture of a computer, holding spots for numbers, how to put addresses on a line to get it from memory, and how to go through making decisions if this is true or if that's true. That was the architecture of a computer. I said, "I wonder how you design them." I went back to elementary school and middle school and the projects that I built out of logic gates. I said, "Can I sit down and draw all the logic gates on many sheets of paper that would add up to a computer?" It took me many, many months at first, over and over trying to figure things out. Self-taught. There was not a single book on how you design these things that I used. I eventually was able to design a mini computer. Around the end of high school, minicomputers were starting to come out. That's 1968. They were coming out from various different companies. But how could I ever hear about one? How could I ever get any information? I was so interested in computers and there was nothing in the local libraries, not even the scientific bookstore, anything on computers. But we had the CERN of its day, Stanford Linear Accelerator Center, the highest level physics research place in the world, and it was nearby. I found out that smart people don't lock doors. It's a strong metaphor. So I would drive in on a Sunday and always find at least one door open on the main building and I could go up to the second floor. I'd usually do it on a Sunday, nobody there. I'd be reading computer magazines and journals and I could send cards to the manufacturers and they'd send me their manuals of the computer describing the architecture. So I started practicing just designing everyone I could: all the Varian computers, all the IBM computers, all the Digital Equipment computers, the Data General ones, the Hewlett-Packard computers. I would sit down on my weekends just designing them. Could never show anyone. Could never get any credit for it. It's just the thing I loved so much in my heart. I thought about if I had a design that was 78 chips, I'd go to bed thinking, can I combine some chips or get a chip to do two things at once? Can I get it down to fewer chips? 76 chips maybe. I got really good at that. I praised myself. I didn't have a class that gave you a grade based on whether you complete a design. For me, it was how simple was it, how did I get fewer parts than other engineers would ever think of. I came up with tricks in my head. But the more important thing was I had the ability to come up with tricks to use fewer parts. So this was my life. At the end of high school, I told my dad, "I'm going to have a 4K Data General Nova computer." I had posters on my wall in my bedroom of computers. Nobody even knew what a computer was back then. And I'm going to have a 4K Data General Nova. 4K is enough to have a programming language where I can have an idea, something I want to solve, type in a program, and get the answer. You need at least 4K for a programming language the normal way. Other than that, you have switches and lights and you turn on ones and zeros. I understood those. Push a button and they go into a little address register, put in some more switches, switches up to ones and zeros, and that little data that was ones and zeros will go into the memory location and the next one and the next one, and then you can say run a program at one by toggling all these switches and lights. That was my life. Anyway, I designed all these mini computers. My dad said it'll cost as much as a house. That's when I sat for about two seconds and I said, "I'll live in an apartment." Who does that when you're in high school? When there's no computers ever in the world, nobody's ever gotten close to one. I'll live in an apartment. I really wanted a computer in my life because I knew how they worked and that was going to come true. Also, I was in Silicon Valley and got to see the changing from... I learned how to design things with vacuum tubes mostly while I was in high school and the world was going to transistors made out of silicon. The reason Silicon Valley is called Silicon Valley now: the inventor of the transistor moved to Silicon Valley and had a company, and when it failed, a bunch of engineers split off and formed other companies and other companies, and then they came up with the idea to make a chip. I was at a show, I might have been seven years old with my dad, a show in San Francisco called Wescon. I went to one booth and a guy held up a poster, a piece of white paper poster, and it showed all these kind of like building tops and connecting roads and he said, "This is a chip we're going to make with six transistors." Six transistors. Oh my god, my six transistor radio was the best gadget of my life. I could listen to music all night long. I asked my dad later that night at home, "Are we going to have better six transistor radios now?" He said, "Oh, no, no. The new technologies are way too expensive. They're for the government, for the military. They can afford them. They don't go to people." I didn't tell my dad, but in the back of my head, I said, "I want to build things for people in their normal lives, in their homes that they really want to use. I want to enhance that. My real reason for being an engineer is to make better appliances for the average Joe in the average home." I kept that in my mind. I knew computer architecture, how computers were developed. You had processors that could operate a bunch of instructions one at a time, get in and out of memory, and you could write a program for a processor. They all came out with all these mini computers that had switches and lights for the input and the output. I built one of those. Finally, I was working one year after my second year of college. I worked for a year programming and an executive got me the chips I needed. I could never afford a single chip. It cost like $50 back then, $500 now. You think a little kid could afford a chip. He got me the chips and I built a little computer that I designed called the Cream Soda Computer. My friend Bill Fernandes and I would ride our bikes down to the store and get green soda and drink it while we were wiring up my design. That was when I met Steve Jobs. I don't know, I just loved... You have different kinds of people. Some are engineering smart, go to the university, get A's in all the courses, and you know how to design this and that and you know how it's been done. But there's other types that are more like inventors. You talk to them and they're really talking about the far out things in the world, almost science fiction things, trying to bring it to reality. I was one of those inventor types, not just an engineer.
