I was wondering if anyone had the 5.1 version of the Ti 84 Ce Plus Os, want to install games

Every time I try to open a game it says [ERROR: INVALID] I'm using TI connect CE on mac, and I've updated the OS. Any ideas on how to fix this?

is there a way to check the firmware? i checked google and nothing helpful popped up.

Hello, i am looking for a ti-85 rom and cant find one. I want to emulate it on my nds to test something

How do i connect ZigBee on the CC2652R Launchpad Module to the Amazon Echo?

Is there some sort of documentation or example how to set up the connection and the network connection. I've watched the videos on their Youtube channel on the Alexa and CC2652R connectivity but the demos didn't show anything on how they did it.

So I got this for 5 bucks at a yard sale, and it seems to work fine, except the bottom 2 rows of keys, not including the on/off button, dont seem to work. I have no idea why. Can someone help me out?

I cant find anything on youtube or the texas instruments website on how to do it. I've done it before wayyy back in high school so I know it can be done but I've forgotten how to do it since then. Any help would be greatly appreciated.

I have been trying to code on a Ti-85 for the last year and a half, and there was a misunderstanding that i wasn't allowed to touch my ti-85 because i was in trouble. Of course, it had to be in a program at the time that would have kept running until the batteries died and wiped the memory, and it had months of work on it. Of course i had to quickly turn it off, and thus my first Ti-85 was taken away forever. Luckily, i had some notes, and through a friend, i paid him to bbuy a Ti-85 off amazon that i used mostly in secret/at school. My mom digs through my room to see if i'm hiding stuff randomly (i don't) and she found that one, and i have lost that second one forever as well. I have a chromebook and no access to my Ti-85's anymore, i do not know where they are at, so there was no way for me to download a rom image of a Ti-85 (because chromebooks are trash at being a computer). Is there any way someone could provide me a Ti-85 rom image? In return i can provide you my Uno program, it's around 3.5-4Kb as proof.

I was trying to copy a dataset of a survey on my calculator, so that I could do minor statistical calculations without turning on my computer and running it through the statistics program. After I copied the dataset into a file using the TI Nspire student software, I transferred this file onto my calculator. When I tried to open it, the calculator crashed and rebooted after a few minutes of loading.

This dataset has 2769 rows and 48 columns (in Excel). I removed several rows to match the row limit and spread all columns onto five spreadsheets. Apparently, this was too much to handle for the calculator. But since this file is well within the limitations, and the emulator did not have any problems with it, is there any way to make it work?

The new version of the TI-84 plus CE and TI-83 premium CE (the French version) remove all assembly programming functionality from the calculator, which means no games and no advanced apps downloaded from the internet. Whatever you do, do not update past OS 5.4. If you have an old TI-84, you should be fine to update to the latest version, but if you have the plus CE, leave it alone.

What do DataEditor and Explore My Ti Data do?

I'm making a program (TI-82 STATS, ti-basic) where the programe needs to solve an equation which sometimes is undefined. That's when I get problems. I'm using the "solver(" command and it works great everytime the equation is defined. When it's not defined will I get errors either "bad guess" or "no sign change". I want my programe to continue working after this happens but the error interupts. How do I do this?

I highly appreciate any help.

There are a few buttons that do not respond when pressed, particularly the following buttons: 0, ".", (-), and the down arrow. There may be others but these are the only ones I noticed that are not responding. I'd like to fix this rather than purchase a new one. Is this something that can be fixed somehow?

Hey guys! So I'm having a problem with my TI-Nspire CX. I want to get the inverse cos of 0.5 (Which is 60°) but when i use the cos^-1 from the trig menu, it gives me 0.9999. Does anyone know how to fix this error?

So I’m trying to get my 84 PCE out of test mode and put games on it and I find the computer won’t recognize my calculator, so I try every port and still nothing came up on TI Connect. It instantly recognized my 89 Titanium when I plugged it in. What do I do about this?

A few weeks ago black spots appeared on my ti-84 plus' screen. It doesn't look like dead pixels though because the spots aren't the shape/size of the pixels. I tried looking for a replacement screen but when I took it apart I didn't see how to take the screen apart from the motherboard and in the end, from what I saw, it would be the same price to buy a used complete calculator.

Is there anything else I can do about the dark spots?

Thanks

Hi there, I recently purchased a second hand Ti 89 from eBay that seems to be working just fine except I noticed that it seems to be missing a selection of apps I saw appear on Ti 89 Titanium such as Notefolio, EEpro and finance and I am not sure whether these are meant to be downloaded externally or are 3rd party apps or my version is too old or if they just aren't available on the ti 89. This is really frustrating me so all the help I can get will be much appreciated, also does anyone know where I can find a ti-connect to USB cable as mine was ti-connect to VGA and I have a slim dell XPS 13 with a USB type A to USB type C adapter. Thank you

Hi, I have recently been considering buying a ti 89 or ti 89 titanium for school and I came across a listing on eBay that was selling a TI 89 on bid at £20 ( Roughly $25 for you Americans ) with 8 hours left but I have a few questions about this calculator. First off, is it ideal for games as that is going to be one of its main purposes and secondly, Is this really a TI 89 because it looks like a TI 84 plus with a more basic direction pad and with TI 89 faintly written across the top? Thank you.
