both graphics and characters.

The T4400SXC internal display controller supports Video Graphics Adapter

(VGA) functions on the internal display devices.

o Keyboard

An easy to use 82/84-key keyboard with full-size keys and standard spacing is

compatible with IBM standard software.

(]

Batteries

The T4400SXC has three different batteries: a main battery, a backup battery,

and a Real Time Clock (RTC) battery.

o Expansion port

TheT4400SXC has one unique 150-pin expansion port.

o Parallel port

A centronics compatible parallel interface port serves two purposes. The port

can

used to connect a centronics compatible printer

an external floppy disk

drive.

(]

RS-232-C port

The T4400SXC has one 9-pin serial interface port.

o Tenkey port

The

T4400SXC has a tenkey pad interface connector on the left side that can be

connected to an external tenkey pad.

o Mouse port.

The

T4400SXC has

one

6-pin mouse port on the back that can

connected to

PS/2 mouse.

o RGB port
