The TI-Nspire CX is the most powerful calculator produced by Texas Instruments, and because of this, there are many emulators that run on it. In order to get emulators to run, Ndless must be installed on the device. Note that while many programs for the Nspire CX will also work the Nspire, some will not work due to the Nspire having less RAM and a grayscale display.
Between the TI-84+, the TI-84+ Silver Edition, the TI-84+ C Silver Edition, and the TI-84+ CE, there a few emulators that run on this family of calculators. Most programs for the TI-84+ will also run on the TI-83+ and TI-83+ SE, and they are included here for completeness.
