1.1 Features

The 100CS is one of the lightest and most advanced portable computers available. Utilizing

advanced technology and high-speed components, the computer offers multimedia functions,

excellent display legibility, battery operation, and IBM PC/AT compatibility. The unit con-

sists of the following features:

❑Microprocessor

A Pentium ®processor with Voltage Reduction Technology (VRT) that operates at 75

MHz and 3.3/2.9 volts.

❑Memory

Standard 8 MB of CMOS RAM. This includes 640 KB of conventional memory and

7360 KB of extended memory.

❑Hard Disk Drive (HDD)

An internal 528 million byte (520MB) HDD.

❑Floppy Disk Drive (FDD)

A 3.5-inch FDD supports 2HD (1.44 MB) floppy disks and 2DD (720 KB) floppy

disks.

❑Display

A 10.4-inch Dual-scan Supertwist Nematic (DSTN) color LCD with 640 x 480 pixels.

The built-in display controller supports 640 x 480 resolution with 64k colors capability

on the internal LCD and up to 1024 x 768 resolution with 256 colors on an external

CRT.

❑Keyboard

An easy-to-use 82/84-key keyboard provides a numeric keypad overlay for fast nu-

meric data entry or for cursor and page control. The keyboard supports software that

uses a 101- or 102-key enhanced keyboard.

❑Batteries

Three different batteries: a main battery, a backup battery (for memory backup), and

an RTC battery (for Real Time Clock).

❑Expansion memory slot

An optional 8, 16, or 32 MB memory module can be installed in the memory slot.

1-2 100CS

❑Parallel port

This port can be used to connect a Centronics compatible printer or other parallel

device. The port supports ECP (Extended Capabilities Port) conforming to

IEEE·1284.

❑Serial port (9-pin)

The serial controller is 16550UART compatible. This port can be used to connect such

serial devices as a serial printer, serial mouse, or external modem.

❑RGB port

The female, 15-pin, D-shell connector can be connected to an external SVGA monitor.

❑Ext. Keyboard/Mouse port

Either a PS/2 compatible keyboard or a PS/2 compatible mouse can be connected to

this port. The computer automatically recognizes which device is connected.

❑PC card slot

A PC card slot supports up to two Personal Computer Memory Card International

Association (PCMCIA) standard version release 2.0 cards. The upper and lower slots

can each accommodate one Type II (5.0 mm) card, or the lower slot can accommo-

date one Type III (10.5 mm) card when the upper slot is empty.

❑Enhanced port replicator port

This port enables connection of an enhanced port replicator. The enhanced port

replicator has two PC card slots (Type III), and expands connections to the following

devices: PS/2 keyboard, PS/2 mouse, serial port, parallel port, external CRT, AC-in,

and AC-out. The NoteDock does not support the following ports: floppy disk, audio

in - audio out, joystick, and selectable ID.

❑AccuPoint

A pointer control stick, located in the center of the keyboard, provides convenient

control of the cursor without requiring desk space for a mouse.
