I don't usually like to use calculators because I find them deskilling on my number work. When I am required to use one I always make mistakes but I never know until I check the answer even when I write down the entire working in great detail. I am borrowing this Ti 92 II and the screen size really helps me see my working out.




I brought a Ti 92 plus. I don't like bidding but I thought it was necessary incase anything happened to this one I am borrowing. It was the only one on there and Amazon would charge me a lot more money to have one shipped.




As you can see the display is not very clear on the Ti 92 II compared to the Ti Plus. I had to even turn on the flash to make the screen visible on the picture or maybe it is wearing out.

Some leads I brought. A usb and a serial lead as some applications require a serial port connectivity on the other end. What I like on the usb lead is the see through shielding and the copper or gold connector.




Also I am pleased to see a calculator based ranger on its final minutes. I took the opportunity so I can experiment with motion on a graph.




I am very pleased with it and I make fewer mistakes as being able to go back, check and make corrections before doing a calculation that might be wrong from key slips. The key grip is the thing I like. My fingers don't slip compared to the previous Casio calculator I had and some ordinary sized ones. Most importantly no scratches to the display. I was a bit worried about that at first.

I was going to buy a newer Texas Instrument calculator initially but I was unhappy with the layout and the missing diagonal arrows. I will state the rest in detail later.

I know these are about 8 to 10 years old but what do you think of the design?

I was thinking of buying one of these before making my choice on the TI 92 plus but considering it is missing the diagonal arrow keys with the f keys at the bottom the screen and not the side with no thumb grip I think they are the trade offs of trying to make it into a pocket sized calculator from the match on the corner. I think I could easily drop that by judging how small it is and for the size of the keys my fingers could slip like on the other smaller calculators I used.

I would like try one of these before I make any definite conclusions but it seems non existent in all the shops I been to. I only recently heard of the Ti 92 as from the one I am borrowing.
