Steve Wozniak: Engineer – Explore Steve Wozniak’s Work
(Lecture Hall bursts with a cacophony of excited chatter. Professor Armitage, a man with a wild mane of grey hair and a twinkle in his eye, steps onto the stage, holding a well-worn Apple II.)
Professor Armitage: Alright, alright, settle down, you budding silicon savants! Today, we’re not just talking about computers. We’re talking about magic. We’re talking about the man who, more than anyone else, put that magic in your hands. We’re talking about the wizard of Woz, the master of minimalism, the… (he pauses for dramatic effect) …the downright delightful Steve Wozniak! 🧙♂️
(Cheers erupt from the audience.)
Professor Armitage: Now, I know what you’re thinking. "Steve Jobs! Visionary! Marketing Genius!" And yes, he was. But let’s be clear: without Woz, there’s no Apple. No iPhone. No late-night Doom sessions on your dorm room computer. 👾
(He holds up the Apple II.)
Professor Armitage: This, my friends, is where it all started. This isn’t just a computer; it’s a testament to the power of pure, unadulterated engineering genius. So, buckle up, because we’re about to dive deep into the mind of a true innovator. We’re going to explore the work of Steve Wozniak, and I promise you, it’s going to be a wild ride! 🎢
I. The Early Years: Pranks, Blue Boxes, and a Burning Desire to Build
Professor Armitage: Wozniak wasn’t born a computer guru. He was made one. From a young age, he was tinkering, experimenting, and generally causing a delightful amount of chaos. His dad, an engineer at Lockheed, instilled in him a love for electronics and problem-solving.
(A slide appears showing a young Wozniak with a disassembled radio.)
Professor Armitage: He built his first computer, a simple adder-subtracter, at the tender age of 13. Thirteen! I was still trying to figure out how to untangle my headphones at that age. 🎧
Professor Armitage: But Wozniak wasn’t just about serious engineering. He had a playful side, a mischievous streak that led to some… interesting… projects. Enter the Blue Box.
(A slide appears showing a schematic diagram of a Blue Box.)
Professor Armitage: The Blue Box, for those of you who aren’t familiar, was a device that allowed you to make free long-distance phone calls. Illegal? Absolutely. Did Woz and Jobs make a fortune off it? Not really. But it was a crucial experience. It taught them about electronics, about marketing (albeit slightly shady marketing), and about the power of technology.
Here’s a quick rundown:
| Project | Description | Key Learning | Fun Fact |
|---|---|---|---|
| Adder-Subtracter | Wozniak’s first computer, built at 13. | Fundamental understanding of digital logic and computer architecture. | He used relays and cardboard! Talk about low-budget innovation! 💰 |
| Blue Box | Device to make free long-distance phone calls. | Electronics, teamwork with Jobs, and the potential (and perils) of technology. | They once prank-called the Vatican pretending to be Henry Kissinger! 📞 |
| TV Jammer | Device to interrupt TV signals. | Understanding of radio frequencies and signal disruption. | He used it to interrupt commercials, much to the annoyance of his neighbors. 📺 |
Professor Armitage: The Blue Box was more than just a prank; it was a proof of concept. It showed Wozniak that he could build something complex, something useful (or, at least, usable), with his own two hands. And that realization was the spark that would ignite the Apple revolution. 🔥
II. The Apple I: A Humble Beginning with a Big Impact
Professor Armitage: After dabbling in HP calculators and various other engineering projects, Wozniak’s attention turned to… well, let’s be honest, a glorified hobby project: creating a computer for himself and his fellow members of the Homebrew Computer Club.
(A slide appears showing a picture of the Apple I.)
Professor Armitage: The Apple I, as it was christened, wasn’t exactly a sleek, user-friendly machine. It was a bare circuit board, requiring users to supply their own case, power supply, and keyboard. But it was revolutionary. It was one of the first single-board computers, and it was incredibly easy to use.
Professor Armitage: Wozniak’s design philosophy was all about simplicity and elegance. He wanted to create a computer that was accessible to everyone, not just hardcore engineers. He stripped away unnecessary complexity, focusing on the core functionality and making it as efficient as possible.

- Price: Relatively affordable at $666.66 (a coincidence, Wozniak insists! Although he did like repeating digits). 😉
Professor Armitage: The Apple I wasn’t a commercial success on its own. Only about 200 were ever made. But it laid the foundation for something much bigger. It proved that Wozniak could design a computer that was both powerful and accessible. And it convinced Jobs that they could turn this hobby into a business. 💰
III. The Apple II: A Revolution in a Plastic Case
Professor Armitage: Now, we come to the pièce de résistance, the magnum opus, the… (he strikes a dramatic pose) …the Apple II!
(He holds up the Apple II again, beaming.)
Professor Armitage: This, my friends, is the computer that changed everything. It wasn’t just a hobbyist’s kit; it was a fully assembled, ready-to-use machine that could be plugged into a TV and used by anyone. And it was all thanks to Wozniak’s genius.
