Setting the CPU Clock Speed

This option lets you set the default speed at which your

computer’s processor operates when you turn it on:

High speed (16 MHz)

Low speed (8 MHz)

Auto speed.

When it is running at high speed, the

TURBO

light on the

front panel is illuminated.

At high speed, it can access memory faster, so your programs

work faster. You should use high speed for everything you do

unless you are using an application program that requires the
slower speed. Some programs (especially older ones) have

specific timing requirements when accessing diskettes, Check

your application program manual.

You can also set the processor to change speed automatically.

This enables the computer to switch to low speed whenever it

needs to access a diskette but run at high speed for all other
operations.

Select

High speed

for 16 MHz,

Low speed

for 8 MHz, or

Auto speed

to have the computer switch to low speed

automatically when necessary.

Note

You may not want to use the automatic setting for

certain

copy-protected programs. See “Changing the Processor

Speed” in Chapter 4 for more information.

In addition to selecting the default operating speed through
SETUP, you can change the speed temporarily by giving a
keyboard command or by running the ESPEED program. See

“Changing the Processor Speed” in Chapter 4 for more

information.
