200 Series 1-1
1.1 Features
The 200CDT/200CDS (200 series) is one of the lightest and most advanced portable comput-
ers available. Utilizing advanced technology and high-speed components, the 200 series
offers multimedia functions, excellent display legibility, battery operation, and IBM PC/AT
compatibility. The 200 series system unit consists of the following features:
❑Microprocessor
An Intel Pentium processor with Voltage Reduction Technology (VRT) that operates
at 100 MHz and 3.3/2.9 volts.
❑Disk storage
The 200 series has an internal 1.3 billion byte (1.26 GB) or 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 for connection as an external device.
❑CD-ROM Drive
A full-size, six-speed CD-ROM drive module can be installed instead of the FDD
module. The CD-ROM drive contains an ATAPI (AT attachment packet interface)
interface controller, and supports the following formats: audio CD, photo CD, CD-
plus, 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
compatible with the Lotus/Intel/Microsoft Expanded Memory Specification (LIM-
EMS).
❑Display
The 200CDT has an 11.3-inch, Thin Film Transistor (TFT) color LCD with 800 x 600
pixels. The 200CDS has an 11.3-inch Dual-scan Supertwist Nematic (DSTN) color
LCD with 800 x 600 pixels. The built-in display controller supports 800 x 600
resolution with 16M colors capability and up to 1280 x 1024 resolution with 256
colors on an external CRT.
❑Keyboard
An-easy-to-use 82/84-key keyboard provides a numeric keypad overlay for fast
numeric data entry or for cursor and page control. The keyboard supports software
that uses a 101- or 102-key enhanced keyboard.
1-2 200 Series
❑Batteries
Three different batteries: a nickel metal hydride (Ni-MH) 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.
❑Parallel 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.
❑External monitor port
The female, 15-pin, D-shell connector can be connected to an external SVGA moni-
tor.
❑PS/2 mouse/keyboard 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
A PC card slot accommodates two 5mm cards (Type II) or one 10.5mm (Type III)
card, which support PCMCIA Release 2.01 cards. These slots also support advanced
cards, including PC Card 16 multifunction cards as well as the Zoomed Video (ZV)
port, which is dedicated to high-performance video data transfer such as MPEG video
playback.
❑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, AC-out, and rotary
switch (ID select switch).
❑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.
200 Series 1-3
❑Infrared port
Incorporates an IrDA1.0 (115.2Kbps supported) standard infrared transmitter and
receiver.
❑Sound System
A Sound Blaster Pro 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.
