Power Macintosh G3 (1997)
The Power Macintosh G3, commonly called "beige G3s" or "platinum G3s" for the color of their cases, is a series of personal computers designed, manufactured, and sold by Apple Computer 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, which was innovative for the time as Dell was the only other major manufacturer then doing this.
