It emulates the keystrokes and functionality of the previous TI-83 Plus, TI-84 Plus and TI-84 Plus Silver Edition graphing calculators. This allows the use of the TI-Nspire on exams permitting just the TI-83 Plus based calculators like SAT and ACT.

Within the Datamath Calculator Museum the combination of the TI-Nspire with the TI-84 Plus Keypad is referred as TI-Nspire KBD. To reduce theft of school-owned TI-Nspire's a "school bus yellow" edition  is available.

Texas Instruments achieved the 100% compatibility by storing even the well known TI-84 Applications into the operating system:

Cabri® Jr.
Inequality Graphing
Periodic Table
Probability Simulations
Science Tools
Transformation Graphing
Vernier EasyData™

The TI-84 Plus Keypad supports with its integrated connector the TI-Navigator™ system, the TI Connect software and the 2nd-generation CBL 2™ (Calculator-Based Laboratory) and CBR 2™ (Calculator-Based Ranger).

As of March 2010 a total of five different keyboards are either available for the original TI-Nspire or announced:

TI-Nspire Clickpad (The original keyboard of the TI-Nspire)
TI-Nspire Touchpad (The keyboard of the 2nd generation TI-Nspire in a blue color scheme)
TI-Nspire Touchpad EZ-Spot (Blue yellow color scheme) 
TI-84 Plus Keypad (The original keyboard of the TI-Nspire)
TI-84 Plus EZ-Spot Keypad (Added yellow "School Property" logo)

Texas Instruments introduced already in 1976 an educational calculator with a total of six interchangeable keyboards! Don't miss the rare ABLE (ABstract Linking Electronically) limited function calculator.

Texas Instruments announced on March 8, 2010 the new TI-Nspire Touchpad and Operating System 2.0. The new OS 2.0, including the TI-84 Plus Silver Edition 2.54MP, was released for this TI-Nspire with Clickpad, too.
