If resetting the computer does not correct the problem, you probably need to turn it off and on again. Remove any diskette(s) from the diskette drive(s). Turn off the computer and wait 20 seconds. If you do not have a hard disk, insert the system diskette in drive A. Then turn on the computer.

Changing the Processor Speed

Your computer’s processor can operate at two speeds: fast or slow (8 MHz). The slow speed is available to provide compatibility with older application programs.

When your computer is operating at fast speed, the SPEED 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 application software manual to determine if this is the case.

Some copy-protected programs require the computer to run at slow 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.

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, press Ctrl Alt -. (Hold down the Ctrl key and the Alt key simultaneously and then press the – key on the numeric keypad.)
