Amazon.com Product Description
With more power than most of us had in our PCs less than 20 years ago, the TI-92 Plus graphing calculator is the machine of choice for students and engineers both at the desk and on the go. It comes with over 500 KB of memory and software for working through algebra and other mathematic problems quickly and easily. With the TI Graph Link accessory (not included), you can connect to computers and even download software upgrades. Solve linear and nonlinear equations, use the Pretty Print feature to see equations in textbook format, and work with 3-D surface graphs in real time. The QWERTY keyboard is rugged and easy to use, the 128 x 240 screen is easy on the eyes, and the calculator comes with a durable shell to protect its face when you're traveling or in the field. Additional accessories can turn the TI-92 into a mobile data-collection station, but it's just as useful at home.  Students beware: Some professors and teachers discourage, or even ban the use of calculators like the TI-92 in their classes, so make sure it's OK before you buy. Once you're set, the manual is clear and straightforward--you'll be programming in no time. Ultrageeks will love the assembly-language option, but the rest of us can get by just fine with the regular interface. The old timers might still cling to their slide rules, but anyone who needs a calculator for school or work can see why the Texas Instruments TI-92 is so popular: Its versatility, power, and portability give you the number-crunching power of a computer no matter where you are. --Rob Lightner Pros

 Great buy if you can find one cheap April 23, 2007

Now that the vastly superior Voyager is out, this calculator should come down in price (theoretically). While I think it's ergonomically superior to the Voyager, it's tragically lacking in Flash memory (which the Voyager has in spades!).
The 92 Plus' ergonomics literally allows you to crunch numbers at speeds that to non-QWERTY users would be unthinkable. Like I said, if you can find this calculator for $80 or less, it's a steal. Otherwise, go Voyager and you will never look back.
 awsome calculator March 6, 2007
thanks for the calculator...
calculator was good as new one, even though it was used one and right now I am using this calculator for all my college maths and science calculations. I would really like to thank you Paul...for such calculator....and for your kind co-operation for shipping twice due to my fault providing wrong address and not charging shipping charge twice...
THANK YOU VERY MUCH!!!!!!!!!!!!!

Never a better caluclator in existance.
Used it all thought Calculus classes and Computer Science. It does everything. Fast, smooth, pretty print flawlessly and more memory then a herd of elephants. Even does 3D graphing excellently. Spherical trig? not a problem at all and fully graph it, slice it up and zoom in.
Also a few sites on hacking the TI-92 Plus that you can google for anyone intrested.
Greatest Calculator Ever!! June 16, 2006
1 out of 1 found this review helpful
I am not too happy that TI stopped releasing operating system updates since it's basically the same as the 89 and voyage 200. Other than that, its awesome. The QWERTY keyboard and function key layout is good. The large screen is good. It takes AA instead of AAA batteries so it lasts longer. Pretty print, symbolic manipulation, algebra, and calculus... just awesome. It also does a lot of stuff with units which has been very helpful in several of my enigneering courses.
 NEEDS HIGH CONTRAST DISPLAY!!! January 30, 2005

I'm sure the capabilities are wonderful. That's why I bought it. But, it was so difficult to use - because I couldn't see what was on the low contrast (even with adjustment) display - that it wouldn't have mattered if it had outclassed a Cray. I couldn't program it without getting a headache from eye strain.If it had a decent display, it would be great. Without reasonable input and output display, it is just a piece of junk!
