Apple Macintosh Quadra 650

The Quadra 650 had tray-loading CD-ROM drive. The Macintosh Quadra 650 and the Macintosh Centris 650 are two closely-related personal computers that are a part of Apple Computer's Quadra and Centris series of Macintosh computers, respectively. When the Centris 650 was introduced in February 1993 alongside the smaller Centris 610, it was intended as the start of the new midrange Centris line of computers, a niche formerly occupied by the Quadra 700 which was discontinued. However, that proved confusing, and the Centris 650 was renamed to Quadra 650 in October 1993, with the CPU upgraded from a 25 MHz to 33 MHz. The Quadra 650 was discontinued without a direct replacement in September 1994, although the Power Macintosh 7100, introduced a few months earlier, which used the same case as the 650 (originally used on the Macintosh IIvx), had a similar target audience.
