Steve Wozniak: The Coding Artist Behind the Apple

In the mid-1970s, computers were massive, scary boxes operated by toggle switches and lights. Steve Wozniak sat in his garage, soldered a few custom microchips on a bare circuit board, and did something radical: he plugged in a standard TV monitor and a typewriter keyboard. The personal computer was born.

The Homebrew Computer Club and the Apple I

Wozniak was a legendary member of the **Homebrew Computer Club**—a group of hobbyists who believed technology should be free and accessible to all. While other members were content with kits that required soldering dozens of flashing LED lights, Wozniak wanted a computer that worked like a terminal.

He designed the **Apple I** circuit board, writing the machine code monitor from scratch using hand-written assembly on a sheet of paper. He had no compiler; he translated the code to binary bytes in his head.

The Apple II: The ultimate Hardware Masterpiece

In 1977, Wozniak released the **Apple II**. It was a staggering masterpiece of hardware optimization: it supported color graphics, high-speed game paddles, and had a revolutionary power supply that ran completely silent. Wozniak's beautiful, hyper-efficient circuit routing is still studied as a masterclass in electrical engineering today.
