Who designed the Apple I computer, the first product sold by Apple Computer?

Steve Wozniak designed the Apple I computer.

Wozniak engineered the machine in 1975 and demonstrated it to the Homebrew Computer Club in Menlo Park, California. Unlike many hobbyist computers of the period, the Apple I was sold as a single assembled circuit board rather than only as a kit of loose components.

Steve Jobs recognized the commercial potential of Wozniak’s design and helped arrange its sale. Apple Computer was founded in 1976 by Wozniak, Jobs, and Ronald Wayne. The Apple I was sold through the Byte Shop in Mountain View, California, and is widely regarded as Apple’s first product.

Steve Jobs is often credited generally with Apple’s early products, but the Apple I’s engineering design was Wozniak’s work. The computer did not include a keyboard, display, or power supply, so buyers needed additional equipment to use it.
