The Macintosh Performa (sometimes called Power Macintosh) is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from 1992 to 1997. The Performa brand re-used models from Apple’s Quadra, Centris, LC, and Power Macintosh families with model numbers that denoted included software packages or hard drive sizes. Whereas non-Performa Macintosh computers were sold by Apple Authorized Resellers, the Performa was sold through big-box stores and mass-market retailers such as Good Guys, Circuit City, and Sears.
The initial series of models consisted of the Macintosh Classic II-based Performa 200, the LC II-based Performa 400, and the IIvi-based Performa 600.
After releasing a total of sixty-four different models, Apple retired the Performa brand in early 1997, shortly after release of the Power Macintosh 5500, 6500, 8600 and 9600. The end of the Performa brand at Apple coincided with both a period of significant financial turmoil due in part to low sales of Performa machines, and the return of Steve Jobs to the company.
The Apple Macintosh Performa 405 features a 16 MHz 68030 processor, 4 MB of RAM, 256k of pre-installed VRAM, and an 80 MB hard drive in a compact, easy-to-upgrade “pizza box” case. The Performa 405 is identical to the Performa 400, but the 405 shipped with a 12″ Apple color monitor but only 256k of VRAM.
The educational version of the Performa 405 is the LC II.
