Apple II

The Apple II was an early 8-bit personal computer produced by Apple Computer. It was introduced on April 16, 1977 at the first in San Francisco as the successor to the Apple I, but complete in a molded plastic case. It began shipping about two months later in June and found immediate success that led to an entire series of Apple II-related products.

Design
Steve Wozniak personally designed the logic board of the Apple II and wrote the Integer BASIC interpreter that was included in the ROMs. Steve Jobs supervised the development of the case by Jerry Manock, while Rod Holt designed the switching power supply that generated less heat and avoided the use of a fan.

Replacement
Steve Jobs led several attempts to develop a successor to the Apple II, such as the Apple III in May 1980, the Lisa in January 1983, and the Macintosh in January 1984, of which only the latter succeeded in marketplace. A few months later in April 1984, John Sculley, Jobs, and Wozniak presided over an "Apple II Forever" event in San Francisco, where the Apple IIc was launched, continuing the product line for a few more years.
