Upgrading the processor

The computer is supplied with a Pentium processor. The ZIF (zero
insertion force) processor socket on the motherboard is designed to
accept a variety of Intel Pentium processors.
You can upgrade your processor by replacing it with one of higher
performance. The motherboard supports the full range of
OverDrive processors known at the time of writing.
The system also supports a range of external clock speeds of 50, 60
and 66 megahertz (MHz). The clock speed is set by adjusting
jumpers on the motherboard. Note that the external clock speed is
lower than the processor's internal clock speed, which is usually the
one advertised. The ratio of the internal and external clock speeds is
known as the 'processor clock multiple'.
