Using Your Computer; Changing The Operating Speed - Epson 10020 User Manual

Chapter 2

Using Your Computer

This chapter covers the following basic procedures for using
your computer:

Changing the operating speed

Using special keys on the keyboard
Interrupting 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: 4.77 MHz or
10 MHz. At 10 MHz, the computer performs all tasks faster,
and you will probably use this speed for almost everything you
do. Certain application programs, however, have specific
timing requirements for diskette access and can run only at the
slower speed. See the manual for your application program to
determine if this is the case.
Use the CPU switch on the front panel to change the speed.
To access the switch, open the cover below the disk drives;
press down slightly on the tab to open the cover. Move the
switch left for 4.77 MHz or right for 10 MHz.
