Your computer’s processor can operate at two speeds: fast speed (the speed of your microprocessor) or slow speed
(8 MHz). The slow speed is available to provide compatibility with older application programs.
When your computer is operating at fast speed, the TURBO light on the front panel is on. When the computer is operating at slow speed, the light is off.
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.

You can change the processor speed temporarily by entering one of the following commands from the numeric keypad on your keyboard:
To select slow speed, hold down the Ctrl key and the Alt key simultaneously and then press the - key on the numeric keypad. The speed light turns off.
To select fast speed, hold down the Ctrl and Alt keys and press + on the numeric keypad. The speed light comes on.
