Setting the Processor Speed
Your computer’s processor can operate at two speeds: high or
low. High speed is 25 MHz or 50 MHz (depending on your
model) 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 unless
you are using an application program that requires a slower
speed. Some programs (especially older ones) have specific
timing requirements when accessing diskettes. Check your
application program manual.
