The TI-82 was released as a more user-friendly version of the TI-85, at the sacrifice of many of its advanced features, but with a lower price tag. It was long believed that the TI-82 could not be programmed in assembly, but, as with the TI-85, a loophole was eventually found, making the TI-82 a much more attractive programming platform. The TI-83 and TI-83 Plus have taken the place of the TI-82 as the standard in math and science classrooms and the TI-82 is expected to be discontinued shortly.

» TI Connect
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 Connect will only work on MacŪ computers.

» 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 wih 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-82 using the following key sequence and reading the number on your screen:

Known ROM versions: 3*, 4*, 7*, 8.0, 10.0, 12.0, 15.0, 16.0, 17.0, 18.0, 19.0, 19.006

History: Assembly language programming was not supported by TI when the TI-82 was released. As with the TI-85 and TI-92, the calculator had to be "hacked" to enable assembly programming.

The TI-82 was a mystery for a long time. People passed the idea of assembly language support off as a joke, saying it was impossible. Finally, in the middle of 1997, a shell was produced. This first shell was called OShell-82 (later renamed to OS-82), and it was followed shortly by Ash. These both use a similar approach. The TI-82 uses a buffer (as does the TI-85) that points to the next routine that needs to be called when a key is pressed. When the pointer is changed and a key is pressed we can execute assembly. A dummy variable is used that points to a location in RAM where assembly code is stored.
