option from the menu. Choosing the Quit option gives the application a chance to remind you to
save your document (not an issue with the training disk, but a very important issue if you've
been using an application for writing or budgeting), and it keeps you from quitting when the
application is in the middle of doing something.
Important
If you turn off the computer when the disk drive is reading from or writing to a
disk, you could damage the disk and lose the informa-tion recorded on it. Wait until the disk
drive light goes off before you turn off the power. If something goes wrong and the disk drive
light stays on longer than 45 seconds, you can stop the disk drive by holding down Control
while you press and release Reset (the key marked with a triangle).
If an application doesn't give you a Quit option, you can always quit by turning off the power.
Just be sure to save your work before you touch the power switch.
Switching applications
Once the power is off, you can start up another application by putting the application program
disk in the startup drive and turning on the power, just as you did when you started up the
training disk. But you don't have to turn off the computer's power to switch applications.
There's a better way (better for the power switch and for the circuitry inside the computer).
Instead of turning off the power switch and exchanging the program disks, do this:
Choose the application's Quit option, but don't turn off the computer's power.
Push in on the disk drive eject button, remove the last application program disk you were
using, and insert the one you want to use next.
Hold down the Apple key and Control while you press Reset. Then release all three keys,
starting with Reset.
If it seems awkward, you're doing it right! If it were more convenient, you might press the
keys by accident and restart your application, losing everything stored in memory up to that
point.
From now on, when a procedure calls for you to hold down one or two keys while you press
another, the keys will be shown joined with hyphens (for example, the Apple key-Control-Reset).
Restarting
Switching applications with the Desktop:
You can also switch from one application to another
by using the Desktop. The procedure is explained in the system disk documentation.
Control Panel Program
The training disk gave you a feel for using the Apple IIgs. Now, if you want to, you can change
the feel of the Apple IIgs to suit yourself by using a built-in program called the Control
Panel.
Here are some of the things you can change with the Control Panel:
The color of the text, background, and border displayed on the screen
The volume of the built-in speaker
The responsiveness of the keys
The responsiveness of the mouse
The speed of the microprocessor
Microprocessor speed:
The Apple IIgs's microprocessor can operate at two speeds: at up to 2.8
