A motherboard is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general use.

In 1976, Steve Jobs and Steve Wozniak co-founded Apple in Jobs's parents' home on Crist Drive in Los Altos, California. Wozniak called the popular belief that the company was founded in the garage "a bit of a myth", although they moved some operations to the garage when the bedroom became too crowded.
The Apple I is Apple's first product, designed by Wozniak and sold as an assembled circuit board without the required keyboard, monitor, power supply, and the optional case.
The Apple II Plus was introduced in 1979, designed primarily by Wozniak.
