Another development is the ability to install Flash Applications, which allows the user to add functionality to the calculator. Such applications have been made for math and science, text editing (both uppercase and lowercase letters), organizers and day planners, editing spread sheets, games, and many other uses.

The Flash memory can also be used to store user programs and data. In 2001, the TI-83 Plus Silver Edition was released, which featured approximately nine times the available flash memory, and over twice the processing speed (15

A second version of the TI-83 Plus Silver

Z80 assembly language gives a programmer much more power over the calculator than the built-in language, TI-BASIC. On the downside, Z80 assembly is more difficult to learn than TI-BASIC. Z80 assembly language can be programmed on the computer and sent to the calculator via USB port, written by hand

The TI-83 Plus series are very similar in the languages natively supported by the calculator. These include "TI-BASIC", an interpreted language used by all of TI's calculators, and "TI-ASM", an unofficial name for the native Z80 assembly language on which the calculator is based.
