Setting the Processor Speed
Your computer’s processor can operate at two speeds: high or
low. High speed is 25 MHz and low speed simulates 8 MHz. The
processor is set to operate at high speed (where it can access
memory faster) unless you change it to low or set the speed to
change automatically (when necessary).
When the computer is running at high speed, the TURBO
indicator on the front panel is illuminated.
You should use high speed for almost everything you do since
your programs work faster on high speed. However, certain
application programs have specific timing requirements for
diskette access and can run only at a slower speed; check your
application program manual.
When you set the processor to change speed automatically, the
computer switches to low whenever it needs to access a diskette
drive and runs at high for all other operations.
This section describes how to set the processor speed in the
Setup program. You can also change the speed using keyboard
commands or by running the ESPEED program. See “Changing
the Processor Speed” in Chapter 4 for more details.
Follow these steps to set your processor speed:
1. At the main Setup menu, highlight Processor
speed . The current status appears:
Speed: High
2- 14 Running the Setup Program
