Texas Instruments TI-85 Graphic Calculator

The Ti-85 is a great calculator. But people should be aware of it's limitations in the college setting. For most all students taking just normal maths and calculus it works awesome. However, engineering students should take note. It's very inefficient and complex working with higher tier maths and especially complex numbers found in Electrical Engineering and Phasors, etc. I recommend the Ti-85 for everything up to Calculus 3/4. Differential Equations, Sohpmore+ Engineering courses such as Circuit Analysis, Power, Systems, etc. Definitely go with AT LEAST TI-86 but highly recommend looking at TI-89,

This was purchased for my daughter to use in High School. It does everything she needs and was easy for her to understand. She loves it and plans to use through out her education.

My husband uses it for college. It can be hooked up to the computer to download items. It works great. My husband needed a calculator for college and it had everything he needed plus more.

I bought the TI-Graphic Calculator about a month ago. I was surprised by its age but the battery was still good and it was the one specified by my son's Math for Electronics Tutor. It came in its original packaging and had the book with it. It does not hook up to any computer with a windows program but can be used with a Macintosh computer.
If you are sure what your needs are, and we were, it is a terrific buy at a third of the current cost. It is difficult to find any on the shelves in Office Max, Office Depot, WalMart or Radio Shack who will try to sell you the next model up TI-89 (which the teacher said was not what we needed). You can order a TI-85 but it is over $120 plus shipping.
A good buy if you know your needs.

After having my last TI-85 from 7th grade through college, it finally broke. If they still made that model, I would buy it new, but settled for a used one. I use it everyday at work.

I used this one for Calculus in HS and at the U of Wash Seattle from 93-98. It's a remarkable piece of hardware and brings back fond memories. Even better than many of the newer graphing calcs out there.

its the greatest item i have ever bought. i really like the calculator. i enjoy using it. it works great

I chose to buy the calculator because I am attempting to create a collection to be used in my classroom.

I like what the calculator is meant to do, and the good looks of the calculator.

I dislike the fact that the calculator is totally dead. I've replaced both batteries and the back-up battery, and it's still dead. It was noted to be sold "as-is", so i have not valid complaints, but it seems the seller was aware of the calculator being dead, and could have been more true to it if he had noted it on the sale. It was definately NOT a purchase I was happy to have made after I received the item.

i love calculator with graphics,that was the reason to pay,i have no more to say
they need 100 caracters at least, i do not have somthing more to say . i just fill the space for the sake of the ebay i love

My son need the calculator for school and I didn't want to pay full price for one. It works great and enjoy using it for his class.

i can barely read the numbers on the screen because their resoltuion is so poor. i am not pleased but such is life on auction sites.

WAS EXCACTLY WHAT MY SON NEEDED FOR HIS CLASS!!!! 1/2 PRICE OF WHAT WE WOULD HAVE SPENT AT OFFICEMAX.

I have no idea how well this product works. We gave the calculator to the school to provide a calculator for someone who could not afford one.

Got this for my grandson who is in highschool and it is perfect and does all the graphics necessary. Can get very involved with it so it is just about out of my league but what he needs in school.

This product arrived in better condition than I expected. It was a bargain beyond bargains. My son needed the device for his SAT/Act testing. I appreciated that it arrived quickly and as promised. Great service!!!

Ordered the Texas Instrument TI-85 Graphic Calculator and it was shipped within a week. Had to put a new battery in it but it worked fine.

The manual for the calculator was on a disk. PDF format if i would have printed it for more paritcle use it would have took 356 pages.

it is cheap. thanks aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

I bought a graphing calculator about three weeks ago. i am very impressed with the very performance of the product, even though its used.

Its cheap, working perfectly, therefore its great for me.
It didnt came with a manual so understanding it is a bit problem for me.

Snazzy calculator, does lots of cool stuff, especially like the conversion and constant functions...very handy!

meets all neend & expectaions for a backpack calculator ....................................................

I just love the feel of these old TI Calculators. I think they are great quality. Today you can buy a japanese one that probably will do all that this does for 1/2 the price, but it will never feel the same. Yes, there are new calculators that can do more, but quite honestly, anything that this machine cant do is better done on a p.c., which almost everybody owns.

It's just a matter of taste really, but every time I use one these old calculators I enjoy doing it, can say the same about my old Palm pilots :)
