Power Mac

Power Macintosh, later Power Mac, was a line of Apple Macintosh workstation-class personal computers based on various models of PowerPC microprocessors that were developed, marketed, and supported by Apple Inc. from March 1994 until August 2006. The first models were the Power Macintosh 6100, 7100, and 8100, which offered speeds ranging from 60 to 110 MHz. These machines replaced Apple's Quadra series of personal computers, and were housed in cases very similar to systems sold by Apple up to that point.
