Apple's first computer was named the Apple I, and it was introduced in 1976 by Steve Wozniak and Steve Jobs.
Wozniak designed the Apple I as a single-board computer, while Jobs helped market it and arrange its sale. The machine was first demonstrated at the Homebrew Computer Club in Palo Alto, California, and was sold through the Byte Shop.
Unlike many later personal computers, the Apple I was sold mainly as an assembled circuit board. Buyers generally had to supply a keyboard, display, power source, and case themselves. This makes it different from the Apple II, which arrived in 1977 as a more complete consumer product.
The Apple I was produced in a small quantity, commonly estimated at about 200 units. Its historical importance comes less from sales than from establishing Apple as a personal-computer company before it grew into one of the world's most valuable businesses.
