Processor and Secondary Cache
The system uses an Intel Pentium processor with an internal clock speed of 166 MHz,
or 200 MHz. These processors use Intel MMX technology.
The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to
optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit
addresses and data types.
