The Apple ][, introduced at the West Coast Computer Faire in April of 1977, and finally offered for sale in June of that same year, was Apple Computer's first big commercial success. Designed nearly single-handedly by Steve Wozniak (with the power supply having been designed by Rod Holt) as a replacement to the earlier Apple I, the Apple ][ fulfilled Wozniak's wish for a games machine which could play Breakout.

The Apple ][ was impressive for its day, featuring a well-designed plastic case, color output to any home television, BASIC in ROM, a small loudspeaker, game paddles, and at minimum four Kilobytes of RAM (expandable to 48KiB). The Apple ][ was also available as a single board, sans enclosure, to hobbyists who wished to supply their own case, power supply and ASCII keyboard.

At first, the only means of mass storage for the Apple was by cassette tape. The Apple had a built-in interface with which one would connect to a cassette tape machine. In 1978, however, the first disk storage system, the Disk ][, was finally released to many Apple users who had been eagerly awaiting it.
