    This article explains the Dual Speed rating for the processor used in the PowerBook 500 series computers.

DISCUSSION


    Traditionally, Apple has advertised the processor's bus clock speed as the speed of the CPU. In the case of the PowerBook 500 series, this is 33Mhz. On the other hand, the DOS world has advertised the processor clock speed, which is twice the bus clock speed, for certain processors. As this is more of an industry standard, we have begun to publicize the processor clock speed, in this case, 66Mhz.
