Notes

The Centris 650 received a silent RAM upgrade: later models included 8 MB of on board RAM, instead of the initial 4 MB. This increased the maximum RAM from 132 MB to 136 MB.

Introduced in February 1993, the Centris 650 was a faster, more expandable version of the Centris 610. It came in a IIvx-style case, and was powered by a 25 MHz 68040 processor. The Centris 650 sold for $2,700, and was replaced in October by the Quadra 650.
