Apple Macintosh PowerBook 150 - Manual (Page 28)

Part 1 Starting the Macintosh Basics tour
Your Macintosh Basics tour is on the hard disk that’s inside your computer. To
take the tour, follow the steps in this section.
Make sure your computer is turned on. If the screen is dark, try adjusting the
screen (see “Problems Turning On Your Computer?” in Chapter 1) until you
see words and small pictures on your screen.
1 Roll the trackball to move the arrow pointer (
8
) around on the screen.
Place your index finger on the trackball and your thumb on the lower
trackball button. Don’t press either button yet.
Roll the trackball, watching the arrow on the screen. Notice that the arrow
moves in the same direction as you roll the trackball.
You may need to roll the trackball around for a few seconds to “break in” the
mechanism so it works smoothly.
