This is what the standard TravelMate 2000 Computer looks like when it is closed.

Here's how the TravelMate 2000 looks when it is set up and ready to operate.

The Hardware

Taking a First Look 1-3

The Hardware

Let's take a closer look at each part of the computer.

The TravelMate 2000's hardware consists of a system board, keyboard, liquid crystal display (LCD) screen, hard disk drive, I/O (input/output) ports, and other electronic circuits needed to control the display and externally connectable options.

System Board

The system board carries integrated circuits that make up the microprocessor and memory. The system board also contains hardware that controls the screen and keyboard. The optional RAM cards, CRT Adaptor, Internal Modem, and 80C287 coprocessor plug into the system board.

Microprocessor

The microprocessor is the "brain" of the computer. It processes data-or information-at speeds so fast, its performance is measured in millionths of a second. The microprocessor handles information in binary code, using the digit 0 or 1. Any piece of information (e.g., a number or character) is represented by a string of 0's and 1's. For example, the number 23 in binary is 1 0 1 1 1. A 0 or 1 in the binary system is referred to as a bit, the smallest piece of information handled by the processor. A byte is a group of eight bits, and represents a single character or number, such as "H" or "9". The microprocessor in the TravelMate 2000 is a high-speed 80C286 microprocessor, running at a clock speed of up to 12 MHz.

1-4 Taking a First Look

The Hardware

RAM

RAM (Random Access Memory) stores data and application software for the processor. You can write to or read from RAM freely, but once the power is turned off, the data in RAM is lost. RAM size is described by the amount of information (bytes) it can store. Symbols often used for this are "K" and "M". One K byte 1 K byte) represents 1024 bytes and one M byte (1 M byte) represents 1024 K bytes. The TravelMate 2000 has a standard RAM size of 1 M byte. This can be increased to 3 M byte by installing two optional 1 M byte RAM cards.

ROM

ROM (Read-Only Memory) contains factory-programmed information, which remains stored even with the power off. You can never change the contents of ROM. The TravelMate 2000 has two ROM areas. One stores the IPL (Initial Program Loader), BIOS (Basic Input/Output System), and setup and hardware installation functions. These programs are sometimes referred to as firmware. The other ROM area stores the diagnostics program, LapLink program, and the operating system, MS-DOS 4. 0 1. This area is called a ROM disk and is used to install MS-DOS on the hard disk.

Keyboard

You communicate with the computer by typing on the keyboard. Many of the keys work just like those on a regular typewriter. However, as you will see, some of the keys have special functions not available on a typewriter. The TravelMate 2000 keyboard is modeled after the IBM 10l/ 102 -key enhanced keyboard layout.

Taking a First Look 1-5

The Hardware

LCD Screen

The LCD screen acts as a window where the computer sends information for you to view. Information entered on the keyboard, read from the hard disk or a floppy, or sent via a modem, for example, is displayed on the screen. The TravelMate 2000's LCD screen can be set to emulate industry standard display modes, including the VGA mode used by IBM in its latest PS/2 series of personal computers, and displays colors as 16 shades of gray. The illuminated, triple supertwist, LCD screen gives you maximum readability in all lighting conditions with a true black-on-white display.

Hard Disk

The hard disk can store up to 20 M byte of information the equivalent of about 14 high-density floppies-and can write and read data very quickly. This makes the hard disk the best place to keep the programs that you use most frequently.

Connectors

The parallel port is used to connect a parallel printer via the supplied conversion adaptor, and the serial RS-232C port is used to connect an external modem, a serial printer, and other devices that use a serial connector. An expansion bus connector is used to connect the optional Expansion Unit (TI Part No. 2568032-0001) or 3.5-inch Floppy Drive Unit RI Part No. 2568031-0001) to the computer. A numeric keypad connector is used to connect the optional Numeric Keypad (TI Part No. 2568033-0001) to the computer. The external battery connector is used to connect the Add-On Battery Pack (TI Part No. 2568030-0001) to the computer.

1-6 Taking a First Look

TravelMate 2000 Options

Add-On Battery Pack

Attaching the optional Add-On Battery Pack to the rear of the TravelMate 2000 adds 3 hours to the operating time. When the Add-On Battery Pack is installed, you cannot use the 3.5-inch Floppy Drive Unit or the Expansion Unit.

3.5-inch Floppy Drive Unit

Using the 3.5-inch Floppy Drive Unit allows you to store information on 1.44 M byte floppies. The 3.5-inch Floppy Drive Unit also has a port with which you can install a 5.25-inch floppy drive, not available from Texas Instruments, and an external keyboard as well.

Expansion Unit

Connecting the Expansion Unit allows you to expand the capabilities of your TravelMate 2000 Computer. The Expansion Unit supports one full-size and one half- size expansion card.

Numeric Keypad

1-8 Taking a First Look

Connecting the Numeric Keypad allows you to enter numeric data easily. The Numeric Keypad is laid out like the numeric keypad on an IBM keyboard.

M byte RAM Card

Using one or two RAM cards allows you to increase the amount of random access memory in your TravelMate 2000. The memory on these cards can be used as Extended memory or as Expanded memory conforming to version 4.0 of the Lotus/Intel/Microsoft Expanded Memory Specifications.

TravelMate 2000 Options

CRT Adaptor

Installing the CRT Adaptor into the computer allows you to connect a VGA or multi frequency monitor to the TravelMate 2000.

2400 BPS Modem with Send-Fax and MNP Class 5 (Internal Modem)

Installing the internal modem card in the TravelMate 2000 allows you to send Facsimile (fax) information over telephone lines.

Note:

manual provided with the option.

The Internal Modem Card may not be available in some countries. For information on this option, see the

80C287 12 MHz Coprocessor

Adding an 80C287 coprocessor to the system board significantly improves processing performance when you are running programs that support a math coprocessor.

Printers

Connecting a printer to your TravelMate 2000 allows you to produce a hard copy of information you have created. To connect a parallel printer, use the supplied conversion adaptor between the parallel port and the TravelMate 2000 printer port. To use a serial printer, simply connect the printer to the serial port of the TravelMate 2000.

External Keyboards

Using the 6-pin mini DIN connector on the 3.5-inch Floppy Drive Unit allows you to connect an additional IBM PS/2 or equivalent keyboard.

Taking a First Look 1-9

The Software

A computer system needs software before it can carry out any useful task. Without software, your computer is just a collection of electrical components. In order to use computer hardware for tasks like writing memos or balancing a checking account, software is necessary.

Software is a series of instructions that direct the computer to perform specific tasks. Generally, these instructions are loaded from a floppy or a hard disk into main memory where they remain until the software program is exited or the system is turned off.

Your computer needs three levels of software to function - an input/output system, an operating system, and an application program.

 The BIOS (basic input/output system) is stored in ROM on the system board. The BIOS controls the

input/output functions of the hardware itself, according to information received from the operating

system or software program, also known as BIOS calls.

 The operating system is a software program that manages the computer's resources, such as disk

drives and printers. By performing these general routines, the operating system is the base on which

programming languages like GW-BASIC and application programs run. The operating system for

this computer is MS-DOS, version 4.01, and is stored in the ROM disk and on the hard disk.

 An application program is software that helps you perform business and personal tasks such as

word processing, spreadsheet analysis, and graphics presentations. Almost all of the application

programs written to run with MS-DOS on IBM and compatible personal computers can be used with

the TravelMate 2000.

1-10 Taking a First Look

The Hard Disk

The hard disk is a permanently installed magnetic disk. Information is read from and written to both sides of the disk at extremely high speeds by heads that float above the disk surface on a cushion of air. When the disk is not actually being used, these heads automatically "park" themselves out of the way to prevent the disk surface from being damaged by head movement.

Hard Disk Format

The hard disk has a platter, which is divided into cylinders. A cylinder is a collection of tracks in the same position on different sides of the hard disk platters.

The tracks of each cylinder are further divided into sectors. Each sector is numbered and holds 512 bytes of data. The computer locates data on the disk by looking for its sector number.

The hard disk in the TravelMate 2000 is formatted and loaded with software by Texas Instruments during assembly.

Do not

format the hard disk.

Caution: If you format the hard disk, all data on the hard disk will be lost.

Taking Care of the Hard Disk

The hard disk in your TravelMate 2000 computer is specially designed to withstand the rigors of travel: the hard disk heads automatically park themselves when the computer is turned off. However, it is still a precision device and careful treatment will prolong its life.

Follow these guidelines to get the most out of your hard disk's performance:

 Never move the computer when the hard disk is being accessed.

Taking a First Look 1-11

The Hard Disk



Never subject the computer to strong vibration or sudden shocks, especially during

transportation.



You can move your computer with the power on; however, it is a good idea to put the

computer in Standby mode.



Always keep backup floppies of all programs and data stored on your hard disk, just in

case of a hard disk failure. The time spent backing up your data is always worthwhile.

Caution: because of a hard disk failure. Follow the MS-DOS backup procedure in your MS-DOS manual or use a backup procedure provided by your application program. If your hard disk fails, TI service personnel may or may not be able to save some or most of the contents of your hard disk if replacement Is required.



When moving your computer to a location where the temperature is more than 18o F (10o C different

from the present location, do the move in two stages: first leave the computer in a place where the

temperature is somewhere between that of the new location and the old location for about 1 hour.

Then move the computer to the new location. This ensures that the hard disk mechanisms have time

to adjust to the new environment and prevents moisture from condensing on the vital parts.

In case of a hard disk failure, contact Texas Instruments at 1-800-847-5757 for information about

data recovery.

You

should back up your hard disk to floppies on a regular basis to protect against loss of data

LCD Screen

Your TravelMate 2000 displays text and graphics on a triple supertwist, illuminated, liquid crystal display (LCD), giving true black-on-white contrast. The TravelMate 2000 can emulate IBM's video graphics array (VGA), and it displays colors as 16 shades of gray.

You also can connect an external monitor to the TravelMate 2000 if the optional CRT Adaptor is installed. External monitor options are described in TravelMate 2000 Options" in Chapter 6.

Resolution

The screen displays a maximum resolution of 640 dots horizontally by 480 dots vertically. The actual display resolution depends on which display mode you select on the Hardware Installation screen and the display mode your application program is designed to use.

The display adaptor in the TravelMate 2000 allows you to select display modes for the LCD screen. (See the Hardware Installation Screen described in Chapter 4.)
