The Apple II was designed primarily by Steve Wozniak. The system is based around the 8-bit MOS Technology 6502 microprocessor. Jerry Manock designed the foam-molded plastic case,[8] Rod Holt developed the switching power supply,[9] while Steve Jobs was not involved in the design or development of the computer.[10] It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire, and marks Apple's first launch of a computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists.[11]
Byte magazine referred to the Apple II, Commodore PET 2001, and TRS-80 as the "1977 Trinity".[12] As the Apple II had the defining feature of being able to display color graphics, the Apple logo was redesigned to have a spectrum of colors.[13][14]
The Apple II was the first in a series of computers collectively referred to by the Apple II name. It was followed by the Apple II+, Apple IIe, Apple IIc, Apple IIc Plus, and the 16-bit Apple IIGS—all of which remained compatible. Production of the last available model, the Apple IIe, ceased in November 1993.[15]
