Introduction
TI began its dynasty of high-quality graphing calculators eleven years ago with the TI-81, and now they're the most popular calculator maker in the world. Casio, HP, and Sharp all suck. If you don't already know, TI graphing calculators don't just add, subtract, multiply, and divide. They can graph equations, do math with lists and matrices, create statistical plots, and even run programs written in a language similar to BASIC. Some can even be programmed in assembly language. Two calculators of the same model can also be linked to each other via a cable and can exchange programs, graphs, pictures, and other variables. There is even a Graph-Link cable which allows the calculator to be hooked up to a computer. Because of this, there are tens of thousands of programs for TI calculators on the internet that are everything from math and science programs to fast-paced games. Here you'll find everything from hardware specifications of each calculator to hardware add-ons to troubleshooting. Have fun.

Add-ons and upgrades
There is a wide variety of modifications you can make to your calculator. The only "supported" accessory of any use to us is the Graph-Link, but some clever hackers with too much free time have modified their calculators to improve speed, add memory, and even install things like EL backlighting ("Indiglo") and IR link ports. All of these upgrades (except the TI Graph-Link) are unsupported by TI. For info on how to buy or build one of these accesories, click on the appropriate link.

Using the Graph-Link
The Graph-Link is a very useful piece of hardware. It is a cable that connects your calculator to your computer, allowing you to download games onto your calculator, store programs on your computer, write programs on the computer (you'll never have to use that awful calculator keypad again!), including assembly language programs. You probably didn't get a Graphlink with your calculator. There are two kinds: the gray cable and the black cable. The gray cable is light gray, has a small unit in the middle. It comes with an adaptor for a PC's serial port. It is for the Mac and the PC. It costs about $50 and you can get it from TI's online store, TI-Store.com, or several select dealers. The black cable is black (duh), has a serial port connector at one end, and a small thin black box at the end. You then plug a link cable into the other end of the box. Since it is for the PC only, it is cheaper, about $20, and can be found wherever TI graphing calculators are sold. There is also a USB version available for the Macintosh.
