Setting the Processor Speed
Your computer’s processor can operate at two speeds: high or
low. High speed is 20 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.
