  • INTRODUCTION

    The TI-Nspire is a significant departure from previous graphing calculators with its grayscale screen and PDA-like appearance. It uses an ARM processor and features 16 MB of RAM and 20 MB of storage space. With the exception of a TI-84 Plus emulation mode, is not compatible with any of TI's previous calculators. When originally released, it completely lacked programming capability. This was incrementally improved with new OS revisions over the next few years, and currently, development in TI-BASIC, Lua, and ASM/C is possible.
