1-2 Taking A First Look
Learning About Hardware
If you are already familiar with the main components of a computer, you may want to skim the remainder of this chapter and skip ahead to Chapter 2 to learn more about your new TravelMate 3000 WinSX's standard hardware and available options. Otherwise, please continue on.
The TravelMate 3000 WinSX's standard hardware consists of a system circuit board, a keyboard, an LCD (liquid ciystal display) screen, a hard disk drive, a 3.5-inch floppy diskette drive, serial and parallel I/O (input/output) ports, TravelPoint pointing device port, and other electronic circuits needed to control the display and external options.
System Board
The system board holds the integrated circuits that make up the microprocessor and memory. The system board also contains the hardware that controls the screen and keyboard. The optional RAM modules, optional Internal Modems, and the optional 80387SX Math Coprocessor all 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 (for example, a number or character) is represented by a string of O's and I's.
For example, the number 23 in binary code is 10111. 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 3000 WinSX is a high-speed 80386SX microprocessor, running at a clock speed of up to 20 MHz.
Taking A First Look 1-3
Learning About 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. K bytes and M bytes are shown in this manual as KB and MB, respectively.
The TravelMate 3000 WinSX has a standard RAM size of 4 MB. This can be increased up to 6 MB by installing optional RAM modules.
ROM
ROM (read-only memory) contains factory-programmed information that remains stored even with the power switch turned off. You cannot change the contents of ROM. The TravelMate 3000 WinSX Rom, sometimes called firmware, is used to store the IPL (initial program loader), BIOS (basic input/output system), and Setup Program functions.
Keyboard
You communicate with a computer by typing on the keyboard. Many of the keys work like those on a standard typewriter. However, some keys have special functions not available on a typewriter, The TravelMate 3000 WinSX keyboard is modeled after the IBM 101/102-key enhanced keyboard layout.
1-4 Taking A First Look
LCD Screen
The TravelMate 3000 WinSX LCD (liquid crystal display) screen acts as a window for the computer to send information for you to view. Information you enter on the keyboard, or information read from the hard disk or a floppy, or sent via a modem, is displayed on the screen.
Learning About Hardware
You can set the LCD screen to emulate industry-standard display modes, including the vGA (video graphics ar-ray) mode used by IBM in its latest PS/2TM series of personal computers. The screen displays colors as various shades of gray. The illuminated, triple supertwist, LCD screen gives you maximum readability in all lighting conditions with a true black-on-white display. Screen standards are summarized in Appendix H of this manual.
Ports and Connectors
The parallel port (connector) is used to connect a parallel printer. The RS-232C serial port is used to connect a mouse, an external modem, a serial printer, or other device that uses a serial connector. The TravelMate 3000 WinSX also provides a 15-pin connector for an external analog monitor.
The six-pin mini-DIN connector on the left side of the case accepts the TravelPoint pointing device.
Hard Disk
The built-in 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 you turn off the computer or the computer enters the Standby or low power mode, the heads automatically 'park" themselves out of the way to prevent the disk surface from being damaged by head movement.
The TravelMate 3000 WinSX's standard hard disk can store up to 60 MB of information­the equivalent of about more than 40 high-density floppies-and can write and read data very quickly. This makes the hard disk the best place to store the programs you use most frequently.
Taking A First Look 1-5
Learning About Hardware
Hard Disk Formatting
The hard disk consists of a platter divided into cylinders. A cylinder is a collection of tracks in the same position on different sides of the hard disk platter.
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 your new TravelMate 3000 WinSX is formatted and loaded with software by Texas Instruments during manufacture. Do not format the hard disk.
Caution: If you format the hard disk, all data on the hard disk wi1l be erased.
Floppy Diskette Drive
A floppy diskette is a magnetic device that stores information created on a computer. Once data is stored on a floppy, as diskettes are called in this manual, you can access the data whenever necessary, or you can replace the old data with new when you no longer need the old data.
1-6 Taking A First Look
During operation, the floppy rotates inside its plastic casing. As it rotates, the read/write head of the drive moves from one track to another, locating information or finding space available to store new information.
Learning About Options
You can enhance the performance of a standard TravelMate 3000 WinSX by adding hardware options available from Texas Instruments. These options enable you to send and receive data over telephone lines, increase memory, enter numeric data more easily, and several other features.

Taking A First Look 1-9
Learning About 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 diskette or your hard disk into main memory where they remain until you exit the software program or turn off the computer.
Your computer needs three levels of software to functionan input/output system, an operating system, and an application program.
q 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.
q 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 application programs run. The operating system for this computer is MS-DOS, version 5.0.
1-10 Taking A First Look
q An application program is software that helps you perform business and
personal tasks such as word processing, spreadsheet analyses, and graphics presentations. Almost all application programs written to run under MS-DOS on IBM and compatible personal computers can be used with the TravelMate 3000 WinSX Notebook Computer.
