Texas Instruments 3000 - Manual (Page 18)

Learning About Options
Numeric Keypad
The Numeric Keypad option (TI Part No. 2568033-0001) connects to the right side of the
TravelMate 3000 case, enabling you to more easily type numeric data. The Numeric
Keypad layout is similar to the keypad on a full-sized IBM enhanced AT
TM keyboard.
Extra Internal Battery Pack
With an extra internal battery pack (TI Part No. 2566962-0001) you can double the time
you can operate your computer on battery power. You can charge the extra battery in the
computer.
80387SX 20-MHz Math Coprocessor
Adding the 80387SX Coprocessor option (TI Part No. 2566997-0001) to the TravelMate
3000 system board significantly improves processing performance of application programs
that support a math coprocessor.
Note: Use only the TravelMate 3000 Coprocessor option or equivalent. Some
coprocessors exceed the computer's power capacity.
Cables
You can order a parallel printer cable (TI Part No. 25518040001) or a serial interface
cable (TI Part No. 2557455-0001) for use with your computer. Pin assignments for both
cables are listed in Appendix G of this manual.
You also can order a LapLink ® cable and User's Manual (TI Part No. 2567016-000 1) to
connect your TravelMate 3000 to another compatible computer. The LapLink software is
furnished with your TravelMate 3000.
