The TI-84 Plus edition is completely compatible with the TI-83 family. From that well-established platform, this new model adds more speed (a processor that’s 2.5 times faster), an enhanced high-contrast display (eight lines by 16 characters), changeable faceplates, and a suite of 30 applications. And with nine times more memory than the TI-83 Plus (1.54 MB of RAM, 480 KB Flash ROM), there’s plenty of room for even more applications and your own data storage.
Includes a USB Port and cable. It also adds USB on-the-go technology (cable included) that can be used to share files with other calculators or to connect to PCs or optional presentation tools.
