The TI-83 Plus is nearly identical to the TI-83, maintaining backward compatibility but greatly increasing available memory and allowing for flash-upgradable ROM and commercial calculator-based applications.

The TI Connect is the latest link cable produced by TI. It has a higher data transfer rate than the TI-Graph Link cable. It's a USB cable and lets you transfer data files (such as programs) between your calculator and your computer.

» TI-Graph Link
The TI-Graph Link is the older link cable produced by TI. It does not have as high of data transfer rate, but it does work with almost all calculators. It connects to your serial port and like TI Connect is widely used to transfer data files (such as programs) between your calculator and your computer.

From time to time, TI will update the internal code of their calculators to work around bugs, optimize functions, and even add features. This results in several versions of each calculator in the marketplace. You can check the ROM version of your TI-83 Plus using the following key sequence and reading the number on your screen:

Known ROM versions:

• 1.03 (17 Mar 1999)

Assembly language programming capability is built into the TI-83 Plus. Assembly programs written for the TI-83 will not run without modification on the TI-83 Plus; some work is required to port TI-83 assembly programs to the TI-83 Plus.

For software development, we recommend Brass, included with the Doors CS SDK, or SPASM.
