Notes

The Quadra 660av is functionally equivalent to the Centris 660av. It operates in 32 bit mode at all times and cannot be toggled back to 24 bit mode. The Centris 660av has a flexible memory system, meaning that any supported SIMM size can go into any SIMM socket in any order, and they can run with partially populated banks. It doesn't support 1MB, 2MB or 64MB SIMMs however. DO NOT USE COMPOSITE SIMMS IN THE CENTRIS 660av!!
