Notes: The Apple I, entirely developed by Steve Wozniak, constitutes the first Apple product. It was also one of the first to integrate a keyboard interface and a video display terminal circuitry on a single board. This allowed to plug the Apple I to a cheap composite monitor, eliminating the need to purchase an expensive computer terminal.
