Macintosh Performa 600 (1992)
The Macintosh Performa series is Apple Computer's consumer product family of Apple Macintosh personal computers sold through department stores and mass-market retailers from 1992 until 1997, when it was superseded by the Power Macintosh 5x00 series. The Performa series was not a new line of computers, but simply renamed models from Apple's regular line of computers such as Quadra, Centris, LC, and Power Macintosh sold by authorized Apple resellers. The initial series of models consisted of the Performa 200, based on the Macintosh Classic II, the Performa 400, based on the Macintosh LC II, and the Performa 600, based on the Macintosh IIvx.
