Product Description
Texas Instruments, Inc. TI-86 is a graphing calculator with 8 display lines, displaying 21 characters, with 96 KB memory, requires 4 AAA battery(s).
Amazon.com Product Description
Designed with power users in mind, the TI-86 graphing calculator has all the power and functionality of the popular TI-85 but with significant enhancements aimed at students of college mathematics, engineering, and science. The TI-86 includes a function evaluation table, deep entry recall, seven different graph styles with multiple line and shading options, and slope and direction fields for differential equations. In addition, the TI-86 boasts 96 KB of user-available memory--three times more than the TI-85. There's also a new function evaluation table which shows numeric output for function, polar, parametric, and differential equation modes.The TI-86 runs with programs designed for the TI-85 and includes all the same matrix features, but with a new matrix editor that allows the user to view and edit matrices in two dimensions. You can also view multiple lists and attach formulas to those lists for automatic computations. A new aspect of the TI-86 is the ability to customize product functionality with machine language programs downloaded from TI's Web site. Besides the strong graphing abilities, the TI-86 also has powerful calculus features like integration, derivatives, minimums, maximums, roots, and arcs. It also supports Z80 assembly language programming. The 64 x 128 high-contrast pixel screen displays eight lines of 21 characters each plus two levels of display menus. With the TI-86, you can link to other TI-86s and TI-85s via the input/output port, and to CBLs, CBRs, and computers. --Dana Van Nest

 Am I satisfied with my on line TI-86 purchase? November 12, 2009
Larry Jenkins (Garden Grove, CA.)
I purchased 2, my 16 year old needed a TI-86 and my 13 year old told me she needed a TI-84. I opted to purchase 2 TI-86's, but they came with nothing, no booklet, no warrantee papers no cables, AC adapters. Then I put 4 rechargeable 1.25v batteries in it and the screen was so light I could only read the screen in the dark. Then I put in 4 new Dura-cells 1.5v batteries and the screen went so dark we can't read it at all. This means the only way we can read the screen is to use 2- 1.5v & 2- 1.25 batteries.
Now after going through all that with Nathan's TI-86, then we tried Ruth's and found it reacted to battery voltage exactly the same way; so tell me what happens at the end of the class period when the batteries voltage starts to drop; will the screen just get lighter and lighter until they have to change one of the batteries? If I would have known, I would have paid double the price.
So were these, TI-86's Chinese knock-offs?
I would like to get the windows cable, but until I get an A/C adapter that works, I don't dare spend any more on it.

This product was as promised. Seller was very prompt in shipping. Item was in next to new condition. I knew I would find exactly what I needed at Amazon.com. Will definitely shop their site in the future.
Disatisfied with product September 23, 2009
Judith Roberts (Houston, Tx USA)
This is the second time that I have ordered this product. I'm still having a hard collectinf my refund form the first defected item, which is the same item, the TI-86 by Texas Instrument. I will send the second order back, because it is also defected. The first item ordered, it was said by the Yellowstone Company the item was new. The item was not new, I paid for a new TI-86 twice I got a reconditioned item. I do not appreciate it, nor does my corporation. We order things from Amazon.com with confidence that we are recieving what we paid for. That did not happen in this case. I would like to get information on who I need to send this defected product back to, and get my refund.
