Chapter 3
Using Your Computer
This chapter covers the following basic procedures for using
your computer:
Changing the operating speed
Using special keys on the keyboard
Stopping a command or program
Resetting and turning off the computer
Using disks and disk drives.
Changing the Operating Speed
Your computer can operate at two speeds: 8 MHz or 12 MHz.
At 12 MHz, the computer performs all tasks faster, and almost
all programs may be run at 12 MHz. However, some option
cards and application programs require the lower speed. See
your option card or application program manual to make sure
that you can use the higher speed before selecting it.
Use the CPU SPEED switch on the front panel to change the
speed; move it left for 8 MHz or right for 12 MHz.
