Welcome to Power Macintosh

Congratulations on the purchase of your new Macintosh. Your computer is designed to give you the highest performance combined with real ease of use—it’s easy to set up, easy to use, and easy to expand. This book will guide you through the setup procedure, tell you how to expand your Macintosh, and provide many tips on using your new system.

Your Macintosh computer is powered by the new † microprocessor (or “chip”). This microprocessor was designed by Apple Computer, Inc., Motorola, Inc., and IBM Corporation. The † microprocessor uses Reduced Instruction Set Computing (RISC) technology to deliver very high performance at the lowest possible cost. The † RISC microprocessor represents the state of the art in microprocessor design.

Your new Macintosh will run almost all your existing Macintosh software, but for best performance and greatest speed, look for the new software programs designed especially for Power Macintosh computers. You’ll find Power Macintosh programs at any software store that carries products for Macintosh.

Follow the instructions in this

chapter to set up your computer

and learn the basics.

1 Getting Started

The illustration on the next page shows all the equipment you will need to set up your computer and begin using it. (Note that your monitor and keyboard may look slightly different depending on what you purchased.)

Place your equipment on a sturdy, flat surface near a grounded wall outlet. (Your Power Macintosh was designed to be used and carried in the horizontal position, as shown on the next page—it should not be used tipped on its side.) You may place monitors weighing up to 70 pounds (31.75 kilograms) on top of the computer.

Before following the setup instructions in this chapter, you may want to read “Arranging Your Office” in Appendix A (in the section on health-related information) for tips on adjusting your work furniture so that you’re comfortable when using the computer.

IMPORTANT When picking up your computer, be sure to grasp it by the sides. Grasping it by the front or back can cause the computer’s cover to lift off.

When lifting or carrying the computer, always grasp it by the sides, as shown. Do not lift or carry the computer by grasping the front and back.

Plugging in the computer

Before you plug your Macintosh into a wall socket, carefully read all the setup instructions in this chapter. Then, before you connect anything to your Macintosh, follow the instructions in this section to plug it in. The plug grounds the computer and protects it from electrical damage while you are setting up. When you are ready to begin, follow these steps:

1Make sure the voltage switch on the back of the computer is set for the kind of voltage system to which you will be connecting.

The voltage switch must be set correctly to avoid damaging your computer. If you don’t know the voltage used in the country you’re in, refer to the table “Voltages for Different Locations” later in this chapter.

Getting Started

WARNING Setting the correct voltage for your computer does not set the voltage for your monitor even if the monitor’s power cord is connected directly to your computer. To protect your monitor, be sure to use the appropriate adapter or voltage converter, if one is necessary.

Check to see that the voltage switch on the back of your computer is properly set before you plug it in.

If you need to change the setting, insert a small screwdriver here and slide the switch.

Set the switch to show “115” for voltages in the 100–130V range. Set the switch to show “230” for voltages in the 200–270V range.

Installing an expansion card

If you purchased a PCI expansion card for your Macintosh, install it now. (See Appendix B, “Installing an Expansion Card,” for instructions.)

If you don’t have to install an expansion card, go on to the next section, “Connecting a Monitor.”

Connecting a monitor

You can connect many types of monitors to your Macintosh computer, including most standard monitors. See the Technical Information booklet that came with your computer for a complete list.

This section contains instructions on connecting most types of monitors. Monitors from manufacturers other than Apple may require adapters for their monitor cables and power cords. If you are connecting a non-Apple monitor, also refer to the instructions that came with the monitor.

Connecting the monitor power cord

Monitors have two cords to connect: a power cord and a monitor cable. To connect the monitor power cord, follow these steps:

1Place the monitor on top of the computer.

Keep these considerations in mind:

m You can place monitors weighing up to 70 lbs. (31.75 kg) on top of the computer.

m Allow a few inches for air circulation around the computer and monitor.

m Make sure that the top of the screen is slightly below eye level when you’re sitting at the keyboard.

m Position the monitor to minimize glare and reflections on the screen from overhead lights and windows.

For further suggestions about locating your computer equipment, consult “Arranging Your Office” in Appendix A (in the section on health-related information).

Getting Started

2Connect the monitor power cord to the monitor.

On some monitors, the cord is already attached.

3Plug in the monitor power cord.

Some monitor power cords are designed to plug into the back of your computer.

Some monitor power cords must be connected to a grounded electrical outlet, not to the computer. Check the information that came with the monitor.

Getting Started

Connecting the mouse and keyboard

You have a choice of several keyboards for your Macintosh. The way you connect the mouse and keyboard depends on whether the keyboard has a separate cable or a built-in cable.

Connecting a keyboard with a built-in cable

1Plug the mouse cable into the recessed port on the back of the keyboard.

The plug and the port are marked with the ◊ icon (symbol). The positions of the port and icon on your keyboard may be different from those pictured.

By the way: A port marked with the ◊ icon is called an Apple Desktop Bus (ADB) port.

Plug the mouse cable into the recessed port on the keyboard. The flat part of the plug should be pointing down, as shown here.

This cable plugs into the Apple Desktop Bus (ADB) port, marked with the ◊ icon, on the back of the computer.

2Plug the keyboard cable into the port marked with the ◊icon on the back of the computer.

Some monitors have a port to which you can connect the keyboard or mouse. See the information that came with your monitor.

10 Chapter 1

Connecting a keyboard with a separate cable

1Plug the mouse cable into the port on either side of the keyboard.

Most right-handed people prefer to use the mouse with their right hand; most left-handed people prefer to use their left hand. Plug the mouse into the port on the side you prefer.

The plug and the port are marked with the ◊ icon (symbol). Align the symbols before you insert the plug. (The positions of the port and icon on your keyboard may be different from those pictured here.)

By the way: A port marked with the ◊ icon is called an Apple Desktop Bus (ADB) port.

ADB icon

2Plug the keyboard cable (both ends are the same) into the other port on the keyboard.

If you plugged the mouse cable in on the right, for example, plug the keyboard cable in on the left.

3Plug the keyboard cable into the port marked with the ◊icon on the back of the computer.

Some monitors have a port to which you can connect the keyboard or mouse. See the information that came with your monitor.

Getting Started

Connecting other equipment

If you are new to the Macintosh, it’s a good idea to get some experience using your computer before you connect other equipment, such as a printer or scanner. To learn basic Macintosh skills, continue with the instructions in this chapter.

When you’re ready to connect other equipment to your Macintosh, see the instructions in Chapter 3.

Turning the computer on

To turn on the computer for the first time, follow these steps:

1Turn on your monitor.

See the information that came with your monitor for the location of the power switch. On Apple monitors, the power switch is usually located on the front of the unit.

By the way: When the monitor is plugged into the computer, you only need to turn on the monitor once. From now on, the monitor will turn off automatically when you shut down the computer, and it will turn on

automatically when you start up the computer. (If the monitor is not plugged into the computer, it must be turned on separately each time you turn on the computer.)

12 Chapter 1

2Turn on your computer by pressing the Power key on the keyboard.

The Power key is marked with a triangle. Its location depends on which keyboard you have.
