1.1 Features

The 400CS/400CDT (400 Series) is one of the lightest and most advanced portable computers

available. Utilizing advanced technology and high-speed components, the 400 series offers

multimedia functions, excellent display legibility, battery operation, and IBM PC/AT compat-

ibility. The 400 series system unit has the following features:

❑Microprocessor

An Intel Pentium® processor 75 MHz with Voltage Reduction Technology (VRT)

that operates at 75 MHz and 2.9 volts.

❑Disk storage

An internal 810 million byte (770 MB) Hard Disk Drive (HDD). A 3.5-inch Floppy

Disk Drive (FDD) supports 2HD (1.44 MB) floppy disks and 2DD (720 KB) floppy

disks. The FDD can also be installed in an attachment (option with 400CS) for con-

nection as an external device.

❑CD-ROM Drive (option with 400CS)

A full-size, quadruple-speed CD-ROM drive module can be installed instead of the

FDD module. The CD-ROM drive contains an ATAPI (AT attachment packet inter-

face) interface controller, and supports the following formats: audio CD, photo CD,

and ISO 9660.

❑Memory

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

and 7360 KB of extended memory, which can be utilized as expanded memory com-

patible with the Lotus/Intel/Microsoft Expanded Memory Specification (LIM-EMS).

❑Display

The 400CS has a 10.4" full color, Dual-scan Supertwist Nematic (DSTN) LCD 640 X

480 pixels. The 400CDT has a 10.4" full color, Thin Film Transistor (TFT) LCD 640

X 480 pixels. The built-in display controller supports Video Graphics Array (VGA)

for the internal LCD and Super VGA (SVGA) for the 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 computer’s keyboard supports

software that uses a 101- or 102-key enhanced keyboard.

400 Series

❑Batteries

Three different batteries: a Li-Ion main battery, a backup battery (for memory

backup), and a RTC battery (Real Time Clock).

❑Expansion memory slot

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

❑Parallel port

Can be used to connect a Centronics compatible printer or other parallel device;

supports ECP (Enhanced 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.

❑FDD port

Enables a connection of the external FDD attachment if the CD-ROM module is

installed inside the system unit.

❑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 accommodate one

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

❑Enhanced port replicator 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, joystick/MIDI port,

audio line-in, audio line-out, headphone, external FDD, AC-in, and AC-out.

400 Series

❑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.

❑Infrared port

This machine incorporates an IrDA1.0 (115.2Kbps supported) standard infrared

transmitter and receiver.

❑Sound System

A Sound BlasterTM ProTM compatible sound system provides capability to record sound

and play it back with a built-in microphone and speaker. The sound system is equipped

with a volume control dial, headphone jack, microphone jack, and audio line-in jack.
