Apple’s first product was essentially a circuit board in search of a case. The Apple I came as a bare motherboard that hobbyists had to assemble themselves, complete with their own keyboard, monitor, and wooden case. Steve Wozniak designed it, Steve Jobs marketed it, and their parents’ garage housed the entire operation. For $666.66, early adopters got the privilege of building their own computer—a DIY experience that makes IKEA furniture seem user-friendly.
