High Quality Content by WIKIPEDIA articles! The Power Macintosh G3 series (commonly known as the "Blue and White G3", or sometimes just the "B&W G3" to distinguish it from the original Power Macintosh G3) was a series of personal computers designed, manufactured and sold by Apple Computer Inc. as part of their Power Macintosh line. It was introduced in January 1999, succeeding the original "beige" Power Macintosh G3, with which it shared the name and processor architecture but little else; it was discontinued in favor of the Power Mac G4 line in August 1999.
