TI82 
"The restyled TI82 offers a basic set of graphing tools for mathematics and science coursework. The TI82 is the predecessor to the upgradeable TI83 Plus.... Learn about the upgradable TI83 Plus and its available calculator software."  TI This model was a hit when it first came out... It would have to be to survive this long and be "restyled" twice!

TI83 
"The restyled TI83 offers graphing tools for mathematics and science coursework, including statistics and finance. The TI83 is the predecessor to the upgradable TI83 Plus... Learn about the upgradeable TI83 Plus and its available calculator software."  TI This was a pretty good calculator, but has been outdated by the 83 Plus and 83 Plus SE. This calculator does not have an upgradeable Flash rom, and has much less memory than its successors. User Satisfaction: 75% with 1 vote 
TI83 Plus 
"This easytouse graphing tool is essential for classes ranging from algebra through precalculus and biology to physics. It also includes advanced statistics and financial features. Enhanced with Flash technology, this handheld technology gives you the flexibility to add TI83 Plus software applications (Apps) and additional functionality beyond math and science, providing longterm value. These reasons and more have made the TI83 Plus the best selling graphing calculator in the US and Canada. See also the TI83 Plus Silver Edition."  TI This model is TI's most popular and widely used calculator by students of all grades. It is relatively inexpensive compared to the other models, yet boasts a pretty large amount of memory (Yes, that means lots of space for games ;) and an upgradable Flash rom.

TI83 Plus Silver Edition 
Enjoy all the functionality of the TI83 Plus with the added advantage of more memory and speed! All in a new, totally cool silver metallic case. With over 1.5 megabytes of available Flash ROM and 24K of available RAM, the TI83 Plus Silver Edition holds up to 94 Apps. Now it's even easier to download and share Apps because TIGRAPH LINK™ for Windows® is included with the TI83 Plus Silver Edition. The increased capacity and speed also helps users get the most out of any of the hundreds of programs written for and adapted to the TI83 Plus."  TI User Satisfaction: % with 0 votes 
TI85 
"The TI85 has been discontinued. Its replacement for use in the classroom is the TI86. To compare our calculators please visit our comparison matrix."  TI The TI85 was the predecessor to the 86; it lacks the large amount of ram, the new case, and some new features that the 86 has, but otherwise is extremely similar.

TI86 
"Designed for college mathematics, engineering, and science, this graphing calculator's unique userinterface make numeric and graphical analysis of advanced topics easy. A suite of TI86 features is being created for the TI83 Plus and TI89 in the form of free APPS, including: Polynomial Root Finder, Simultaneous Equations Solver, Differential Equation Graphing (built into the TI89), Constants and Conversions (built into the TI89)"  TI This calculator has to be good, why else would I build a web site for it? And why else would TI release new apps for its other calculators to emulate some of its features? I believe it to be TI's greatest acheivement besides the 89. The 86, however, is easier to use and you can do math faster due to a better menu system and various other goodies (such as not having to stick in those annoying close parenthesis marks) than on the 89. Long live the TI86! User Satisfaction: 100% with 1 vote 
TI89 
"Essential for AP Calculus, college math, and beyond, the TI89 is the most logical handheld technology for advanced mathematics studies. Enhanced with Flash technology, this handheld technology gives you the flexibility to add calculator software applications and additional functionality, providing longterm value."  TI This calculator is great! My favorite feature is the "solve(" command ;) It can solve practically anything! It also has many commands for calculus. User Satisfaction: 100% with 1 vote 
TI92 
The TI92 is no longer in production. Its replacement for use in the classroom is the TI92 Plus or TI89. Or look at the TI92 Plus Module which upgrades your TI92 software to a TI92 Plus. To compare our calculators please visit our comparison matrix."  TI This is essentially the same calculator as the TI89, but in a case with a QWERTY keyboard. WARNING: This calculator may NOT be used on SATs due to the keyboard. I guess it classifies as a computer ;) User Satisfaction: % with 0 votes 
TI92 Plus 
"Bring the power of a computer lab to your mathematics classroom. With builtin geometry software, and a powerful math engine, the TI92 Plus is useful in all high school and college math classes.

A few assembly programs have sound... use a speaker to hear it. 
PhoneLinc 
Fission2 Labs' PhoneLinc lets you use a telephone cable instead of the small calctocalc link from Texas Instruments. No modification of the calculator is required!
