History: The Centris 650 was a faster, more expandable version of the 610. It came in a IIvx-style case, and was powered by a 25 MHz 68040 processor. In October 1993, the 650 was replaced with the Quadra 650, which had a 33 MHz 68040 processor, but was in all other ways the same. The Centris/Quadra 650 sold for $2,700, and was discontinued in September of 1994.
