Although officially produced in celebration of the Twentieth Anniversary of Apple, the 20th Anniversary Mac was released close to a year after the fact, in late Spring, 1997. And a truly unique Mac it was. The Motherboard was similar to that of the PowerMac 5500, and it was based on the same 603e processor, running at 250 MHz. The real innovation of the 20th Anniversary Mac was its unique shape, and advanced sound and video features. It came with an integrated TV/FM Radio System, an S-Video Input, and a custom sound system designed by Bose, with integrated stereo speakers, and a separate sub-woofer (it also included a 33.6Kbps GeoPort modem). The Twentieth Anniversary Mac was a limited edition, and sold for nearly $10,000. Its price was cut to as low as $1,999 and it was discontinued in March 1998.
