PC Cards
4-3
Your Extensa computer supports all PCMCIA
and Cardbus PC cards. These PC cards are used
to add functionality to your computer, such as
communicating over a telephone or connecting
to a network.
The computer has built-in slots that support one
Type III or two Type II or Type I PC cards. Type
III PC cards must be inserted into the lower slot.
Your Extensa computer is designed to support
additional functionality on top of the standard
Cardbus interface. These functions include the
Zoomed Video port interface required by MPEG
cards (on the bottom PC card slot) and the
DataRace Speakerphone modems.

PS/2 Devices
4-4
Your Extensa computer supports external
devices that connect to a PS/2 port. Such
devices include an external numeric keypad,
external keyboards, or external mouse.

External Monitor
4-5
Your Extensa computer supports standard
analog external monitors with resolutions up to
1280 x 1024. The computer also supports DDC
compatible monitors allowing you to use the
“Green” monitors (those monitors that meet the
Energy Star standards).
When the computer is connected to an external
monitor, you can use the computer with the
display closed.
You can also display images on the external and
internal display at the same time. This feature
is called SimulSCAN™. To enable this feature,
set the DISPLAY parameter in Setup to Both.
You can also easily switch between the displays
LCD, CRT, or both by using the Fn+F12 hot key.

External Mouse

Your Extensa computer comes with a pointing
device already installed, but you can also use an
external PS/2 or serial mouse.
 To connect a PS/2 mouse, insert the
connector into the PS/2 port in the rear of
the Extensa.
 To connect a serial mouse, attach the
connector to the 9-pin serial port in the rear
of the Extensa.
Note: A serial mouse is not a Plug and Play
device. For Windows 95 to detect a serial mouse,
use the Add New Hardware icon in the Control
Panel.

Memory
4-7
Your Extensa computer comes with 16 MB of
dynamic random access memory (DRAM). Your
computer has one memory slot. You can
increase memory by installing an upgrade
module into the memory upgrade slot on your
computer. You can expand RAM from 16 MB up
to 48 MB.

Caution: TI does not warrant the use of any

Audio Options
4-8
Your computer comes with a set of built-in
stereo speakers and a monaural microphone,
but if you wish to use other stereo equipment,
the computer comes with three audio jacks —
Line-out, Line-in and Microphone-in.
Connecting Audio Devices
Line-out allows you to use a headset or
amplified external speakers. The computer’s
internal speakers are disabled when a headset or
external speakers are plugged in.
Line-in connects to an external stereo source.
This allows you to play an external CD through
the computer speakers, for example, or make a
recording if you have the correct software.
Microphone-in allows you to record input into
the computer through an external microphone.

Mobile Productivity Base Option
4-9
The Mobile Productivity Base (MPB) option is a
full-featured docking module that duplicates all
of the ports on your computer plus additional
ports. In addition to replicating ports, the MPB
docking option also has a removable modular
bay that houses a CD-ROM drive or floppy disk
drive module and supports the Texas
Instruments proprietary Advance PCI card.
The MPB can be used as a desktop only unit, or
be carried with the notebook to make a portable
full function notebook computer.
Refer to the instructions that come with your
docking module for more details.
