The Power Macintosh G3, commonly called "beige G3s" or "platinum G3s" for the color of their cases, was a series of personal computers designed, manufactured, and sold by Apple Computer, Inc. from November 1997 to January 1999. It was the first Macintosh to use the PowerPC G3 (PPC750) microprocessor, and replaced a number of earlier Power Macintosh models, in particular the 7300, 8600 and 9600 models. It was succeeded by the Power Macintosh G3 (Blue & White), which kept the name but introduced a radically different design. The introduction of the Desktop and Minitower G3 models coincided with Apple starting to sell user-configurable Macs directly from its web site in an online store[2], which was innovative for the time as Dell was the only other major manufacturer then doing this.
The Power Mac G3 introduced a fast and large Level 2 backside cache to Apple's product lineup, running at half processor speed. As a result, these machines were widely considered to be faster than Intel PCs of similar CPU clock speed at launch, an assertion that was backed up by benchmarks performed by Byte Magazine, which prompted Apple to create the "Snail" and "Toasted Bunnies" television commercials.
The Power Macintosh G3 was originally intended to be a midrange series, between the low-end Performa/LC models and the six-PCI slot Power Macintosh 9600. It is the earliest Old World ROM Macintosh model officially able to boot into Mac OS X, and one of only two Old World ROM models able to boot into Mac OS X, the other model being the early PowerBook G3.
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. The Power Mac went on to become the mainstay of Apple's top-end offerings for twelve years, through a succession of case designs, four major generations of PowerPC chips, and a great deal of press coverage, design accolades, and technical controversy. In August 2006, the Power Mac's retirement was announced at Apple's Worldwide Developers Conference by Steve Jobs and Phil Schiller, making way for its Intel-based replacement, the Mac Pro.
