When the computer is running at 4.77 MHz, the power

LED is orange. At 10 MHz, the light is green.

You can reset the computer to reload the operating system

or to restart a program. You may also need to reset if an error

occurs and the computer does not respond to anything you
type. Resetting, however, erases any data in the computer’s
temporary memory (RAM) that you have not stored; so be
careful when you reset your computer.

In MS-DOS, you can hold down 

Ctrl 

and press C to stop

a program’s operation and return to the MS-DOS command

prompt. If an error occurs, try this method before you reset the
computer.

Do not reset the computer to exit a program unless you have

to. Some application programs classify and store new data
whenever you exit the program properly. If you reset the
computer while such a program is running, you may lose data.

There are three ways to reset. Because each is more

powerful than the last, try them in the order listed here:

1. If you are using MS-DOS, hold down 

Ctrl 

and 

Alt 

and

press the 

Del 

key on the numeric keypad at the right of

the keyboard. The screen goes blank for a moment and
then MS-DOS reloads. (MS-DOS must either be on the
diskette in drive A or on the hard disk.) If this does not

correct the problem, try the second method.

2. Use a pencil or a similar type of thin pointed object to

press the 

RESET 

button above the keyboard. This method

works even when the keyboard does not respond to your
commands. If this does not correct the problem, try the
third method.
