Besides this manual, you should have the following: The computer and power cord

The Keyboard with attached cable

MS-DOSdiskettes GW-BASIC diskette

MS-DOS User’s Guide

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:

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 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.

1-2

Setting Up Your System

Appropriate power sources:

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 peripheral 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.

Connecting a Monitor

The video display monitor is the device used by the computer

to communicate with you. Your software will use the display information, such as prompts, text, graphics (charts and pictures), etc.

Several types of monitors are available as options. A typical video display system provides a high resolution monochrome (green or amber screen) screen display. Your computer can be used with either monochrome, color video monitors, EGA or VGA monitors.

In addition to the display monitor itself, the video system includes a video controller board. This board generates the letters, numbers, and graphics symbols displayed on the monitor screen.

Connectors are provided for the display type that is supported by the board (monochrome, RGB color, high resolution EGA, VGA etc.). Certain boards support more than one type of display, and may provide a switch to select either color or monochrome modes.

screen to

The procedure you use to connect your monitor to the

computer depends on the type of monitor you have. See your monitor manual for detailed instructions, or follow these general guidelines:

l-4

Setting Up Your System

Place your monitor on top of or near the computer. It is

1. easiest to connect the monitor cable if you are facing the back panels of both the monitor and the computer.

If necessary, connect the monitor cable to the monitor.

2. (Some monitors come with permanently attached cables.)

Connect the monitor cable to the video connector on the

3. back of the computer, as shown below. If the plug has retaining screws, tighten them securely.

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.

The parallel interface on your computer is Centronics compatible and uses a 25pin 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.

2. 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.
