Besides this manual, you should have the following:

The computer and power cord

The Keyboard with attached cable

MS-DOS diskettes

GW-BASIC diskette

MS-DOS User’s Guides

GW-BASIC User’s Guide

In addition to these items, you need a compatible monitor to

use with the computer.

Be sure to keep your packing materials. They provide the best protection for your computer if you need to transport it later.

Choosing a location

Before you set up your computer, it is important to choose the right location. Select a spot that provides the following:

1-2

A large, sturdy desk or table that can easily support the weight of your system, including all of its components: Make sure the surface is hard and flat. Soft surfaces like beds and carpeted floors can generate static electricity, which may erase data on your disks and damage the computer’s circuitry. Soft surfaces also prevent proper ventilation.

Good air circulation. Air must be able to move freely under the system as well as behind it. Leave several inches of space around the computer to allow ventilation.

Moderate environmental conditions. Protect your computer from extremes in temperature, direct sunlight, or any other

Setting Up

Your

System

source of heat. High humidity also hinders operation, so select a cool, dry area. Avoid dust and smoke, which can damage disks and disk drives and cause you to lose valuable data.

Appropriate power sources. To prevent static charges, connect all your equipment to three-prong, grounded outlets. You need one outlet for the computer, one for the monitor, and additional outlets for a printer and any other peripherals.

If it has the appropriate power cord, you can plug your monitor into the auxiliary power outlet on the back panel of the computer, reducing the number of wall outlets you need. (The current required by the monitor must not exceed 1 amp.) If you need more outlets, you may want to buy a power strip available at any electronics store to provide extra outlets. A power strip with surge suppression is recommended.

No electromagnetic interference. Locate your system away from any electrical device, such as a telephone, that generates an electromagnetic field.

Setting Up Your System

Figure l-2. System Main Unit

Connecting a Monitor

The procedure you use to connect your monitor to the computer depends on the type of monitor you have. If you have a VGA monitor (or a multi-frequency monitor with an analog connector), you can connect it to the computer’s built-in VGA port. See “Using the VGA interface” below. If you have any other type of monitor, see “Using a Display Adapter Card” below.

Using the VGA Interface

Follow these steps to connect your VGA monitor to the VGA port on the computer:

Make sure your monitor is turned off.

l-4

Setting Up Your

System

Place your monitor on top of or near the computer. For

2. easy access, turn the monitor and computer around so the backs of both components are facing you.

If necessary, connect the monitor cable to the monitor.

3. (Your monitor may have a permanently attached cable.)

Examine the connector end of the monitor cable, and

4. position the plug to match the orientation of the monitor port. Then insert the plug into the port (the connector should fit in easily when properly oriented), as shown below.

Figure l-3. Connecting a Monitor Cable

Caution To avoid damaging the connector, take care not to bend the pins when inserting the plug.

5. If the plug has retaining screws, tighten them by hand or with a screwdriver, depending on the screw type.

6. Plug the monitor power cord into the monitor’s power inlet, as shown below.

Figure 1-4. Connecting a Monitor Power Cable

Plug the other end of monitor’s power cord into an electrical outlet.

Using a Display Adapter Card

If you are using a non-VGA monitor, you’ll need to install a display adapter (video) card in one of the computer’s option slots before you can connect the monitor. (Your dealer may have already installed the video card for you.)

If the video card has not yet been installed, you’ll need to follow the instructions in Chapter 7 to install an option card. But first, check the following table to make sure your display adapter card and monitor are properly matched.

Setting Up Your System

Monitor/video card compatibility

Monitor Monochrome

Color or EGA

*EGA cards support only EGA monitors.

Video card Monochrome display adapter (MDA)

Multi-mode graphics adapter (MGA) Enhanced graphics adapter (EGA) Hercules graphics card

Color graphics adapter (CGA)

Multi-mode graphics adapter (MGA) Enhanced graphics adapter (EGA)

When you are installing the video card, check to make sure any switches or jumpers on the card are set properly. For example, you may need to change a switch setting to select color or monochrome. See the documentation that came with your monitor or video card for instructions.

Once you have installed your video card, return to this section to connect your monitor to the computer. If your monitor came with its own manual, follow the instructions there.

Otherwise, you can follow the steps in “Using the VGA

Interface” above; just insert your monitor connector into the

video card port instead of the built-in VGA port.

Setting up Your system

1-7

Connecting a Printer, Mouse, or Modem

The computer has a parallel interface and two serial interfaces on the back panel, so you can easily connect a printer or other type of device with either type of interface.

For example, you can use the parallel port to connect a parallel printer (most printers have a parallel interface). You can use

the serial port to connect a serial printer, a serial mouse, or an external modem. Follow the steps in this section to connect a printer or other peripheral device to either the parallel or serial interface.

Using the Parallel Interface

The parallel interface on your computer is Centronics compatible and uses a 25-pin connector. To connect a parallel printer to your computer, you need an IBM-compatible printer cable. If you are not sure which one you need, or whether you

have the right one, check with the store where you purchased the printer.

Once you have the correct printer cable, follow these steps to connect the printer to the parallel interface on the computer.

Place the printer next to your computer.

One end of the printer cable has a 25-pin, male connector.

Connect this end to the parallel port on the back panel of the computer, as shown below.

If the plug has retaining screws, tighten them securely.

Setting Up Your System

Figure 1-5. Connecting the Printer

Connect the other end of the cable to the printer, as shown below. If the printer has retaining clips on each side of the printer port, squeeze the clips together to secure the cable.

Plug the printer’s power cord into an electrical outlet.

Using the Serial Interface

If you have a serial printer, modem, mouse, or any other peripheral with a serial interface, you can connect it to the serial (RS-232C) port on the back of the computer. Your computer uses IBM-compatible, 9-pin, male connector, so be sure you have the proper cable. If you are not sure which one you need, or whether you have the right one, check with the store where you bought the cable.

Setting Up Your System

1-9

To connect a serial device, follow the same steps outlined above for a parallel device, but connect the cable to the serial

port, shown on figure l-4.

Figure 1-6. Serial Ports
