Changing the Processor Speed

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

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

Note

When your computer is operating at high speed, the SPEED light on the front panel is green. When the computer is operating at low speed, the light is amber.

You should use high 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.

Some copy-protected programs require the computer to run at low speed while accessing the program on a diskette. These programs also usually require you to leave a key disk—the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program, you can change the speed to low to access the diskette and return it to high speed when you are finished.
