Texas Instruments TI-92 Graphing Calculator

Probably the best deal for a classic calculator

This is one of the unsung stars of the calculator world. It sports a fast (at the time) processor, a large screen, and an excellent keypad in a unit that seems to hold up very well.

For a collector calculator, they are super plentiful as most of them were retired from high schools, keeping the average price pretty cheap.

It's basically the same electronics as the TI-89 Titanium, but at a much lower price.

The TI-92 as well as the TI-83 & TI-84 are well supported in the hobbyist sector with new homebrew software being developed for it.

I have no idea if it would be allowed to be used in exams. Those days are long gone for me.

And the "TI-92 Plus" has more memory as well as a (much) superior screen.

And all of this coming from an HP guy. :)Read full review

TI-92 Graphic Calculator

Works excellent. It fits hands better than the other style straight one. Super easy to read cause it has bigger screen. Easier to hold feels like a keyboard.. Would recommend it to anyone..

Useful tool with versatile features.

The product/Ti-92 Plus graphing calculator itself is perfect, because it's completely new. However, it would have been better if the four AA batteries were new as well. After I opened the package on the delivery day, all of them were leaking and dark-yellow colored liquid came out so I had to buy/purchase new AA batteries from a convenience store. Since it was leaking, the manual/book got wet too and I had to throw it away instead of keeping it as a reference. Luckily, I know how to use this product without flipping the book/manual so I didn't need it anyway. Overall, I would definitely recommend it to other people, because this product is very suitable for a student like me who studies advanced mathematics. Read full review

I bought a CAS Graphic Calculator TI-92 Plus. This was in mint condition, original sealed packaging. I can confirm it is the genuine artifact. This has the computer algebra system so very useful (obviously not allowed in any exams) but it serves more of a companion for your life long studies and into your careers should you stay in the field involving mathematics. I prefer this as opposed to other modern graphing calculators for the simple fact it takes the standard four AA batteries.Read full review

Good but

The only complaint I have is the brightness of the display. It is very dim and was difficult to read.

Great vintage calculator

TO-92 works great and looks good. It was brand new elsewhere but for almost $200. This one was almost like new.

Perfect for a home electronics project

Plan on using this calculator for a project. Github is designing new motherboards to fit inside and allow smaller computers like raspberry pi to be attached along with changing the screen to a color touchscreen. Calculator works as intended and I’m looking forward to experimenting with it.Read full review

Perfect for math and engineering

This is a classic calculator with a qwerty keyboard. The software is based on Derive from Soft Warehouse. There is a tight integration between numeric and symbolic operations. Unit calculations are native and are easy to use. Read full review
