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:
U High speed (16 MHz)
U Low speed (8 MHz)
U 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.
