Originally released without an FPU, meaning the CPU was the Motorola 68LC040. Later became the Macintosh Quadra 650.
General Information
Expansion
The Macintosh Centris 650 and Macintosh Quadra 800 computers each have three NuBus expansion slots and a processor-direct slot.
PDS
The PDS is connected to the pins of the MC68040 without any buffers. The PDS signals are the same for the Macintosh Centris 610, Centris 650, and Macintosh Quadra 800 computers, but the system clock speeds are different.
Except for timing, the processor-direct slots in the Macintosh Centris 610, Centris 650, and Macintosh Quadra 800 computers are identical to the ones in the Macintosh Quadra computers; the PDS card used with the adapter in the Macintosh Centris 610 is the same except for its size (maximum length of 7 inches).
