Changing the Processor Speed

Your computer’s processor can operate at two speeds: fast or slow. Fast speed is the highest speed at which your microprocessor is capable of running, such as 25,33, or

50 MHz. Slow speed simulates an 8 MHz processor to provide compatibility with older application programs.

When your computer is operating at fast speed, the speed light on the front panel is green. When the computer is operating at slow speed, the light is amber.

You should use fast speed for almost everything you do because your programs will work faster. However, certain application programs have specific timing requirements and can run only at the slower speed. See your software manual to determine if this is the case.
