I charge my ti 84 plus cet python with my PC only. When i plug it out, it doesnt have a sign of charging and the PC disconnects it. Will my calculator charge while its screen is turned off?

My brand new ti 84 ce+ only works when plugged in even if charge is shown to be full.

found an old TI89 in my parents garage, NOT the Titanium version, it still powers on but is permanently stuck, can only turn it off by removing the batteries, I've tried changing them including the back up one but that didn't work, i left it empty for a couple of days and that didn't help either, I searched around and it looks like the OS is corrupted.

It seems you can fix it by re-installing the OS using the TI-Connect app but I don't have the silver cable that is used to connect the calculator to the PC, it seems like a standard 2.5mm to USB Serial but the silver cable has a PCB in the middle of the cable and I'm not sure if that is necessary for it to work.

My question here is, do specifically need the TI-Connect Cable/Silver Cable to connect the calculator to the PC? Or can I use a standard 2.5mm to serial cable to fix the calculator? Are there alternatives? Asking cause the cables seem to be more expensive than the calculator itself lol.

Thanks beforehand

It's driving me crazy needing exact answers but only getting rounded decimals in the table. How can I get a fraction out of them? Is there a way to put table values into the normal calculator so I can math>frac?

If I input a division problem using only whole numbers, it will only give an answer as a whole number, fraction, or equation. I need it to give exact decimals. For example, if I input 5/2, it will return 5/2. However, if I type in 4.4/4, it will return 1.1. If I input sqrt(4628), it will return 2*sqrt(1157)

i have an official TI grey link cable and a 25 pin paralell card in my pc. when trying to use any software to connect to it, it dosnt even show up. ive tried using vmware and passing the lpt port directly into the guest OS and i got the same results on windows 98 and XP. i am running out of ideas.

my setup: ti-86 > grey link > male to male paralell port adapter > star tech paralell port pcie card > vmware 17 > windows XP SP3 with the hardware paralell port passed directly into it.

Im just asking if anyone Has a silverlink or any graphlink cloud you measure the leanght of the Jack (im not taking abouth with but lenght, visualization below)

}==== ]-X __/ | ✓ edit:unfortunetly my visualization broke ):

Has anyone seen a clamshell case for the TI calculators which allows the calculator to slide in? You know, like the cover that comes with them... you can slide it over the calculator face when you're not using it, then slide it on the back when you're pressing buttons. It would be nice if a latchable or zipperable case would use the slide feature, instead of a dumb strap that gets in the way of the buttons. Has anyone seen anything like that?

Good evening, everyone! I'm posting here with some questions about a project I’d love to tackle over the holidays. I’m looking to rebuild my TI-84 Plus CE calculator from scratch, with the goal of maximizing its computing power and adding new features like WolframAlpha integration and more customizability.

I would like to use the shell of my old TI-84 Plus CE but completely revamp the internal hardware. My hope is to make it much more powerful while keeping its core functionality and interface intact. However, I am unsure if this is feasible. I would really appreciate any guidance from the community.

My main questions are:

1. Can I use any existing hardware to build a more powerful version of the TI-84, or would I need entirely new components?

2. Is it possible to reuse the original TI-84 code on new, upgraded chips, or would I need to rework the software entirely?

3. Has anyone here attempted to add functionalities like WolframAlpha integration or other third-party software support? Any suggestions on approaches or compatibility concerns?

4. If anyone has experience with calculator modifications, are there any hardware choices that would maximize customizability, especially for adding new functionalities beyond typical calculator capabilities?

Thanks in advance to anyone who can share insights or point me in the right direction.

Hello fellow nspire users,

I would like to know if anyone else has experienced this phenomenon before and if it can be prevented: if I call a library function that calls itself such that the calculator fails with "Error: Resource exhaustion", then the entire library's set of functions will define themselves in both the current document and any new documents I make afterward. Furthermore, these functions cannot be deleted (DelVar does not throw an error but the function still exists) and cannot be re-defined to something else ("Error: Variable is protected") Resetting the calculator fixes the issue.

I believe this bug can be reproduced by following this procedure:

• Create a new calculator document
• Make a new program editor page for a public library function named "badfunc"
• In the function body, type the single statement "Return badfunc()" and store the function
• Save the document under MyLib in a file called "badfunclib" and refresh the calculator's libraries
• Open a new calculator document. The variable "badfunc" should not be defined, as expected
• Call "badfunclib\badfunc()" so that the resource exhaustion error is thrown
• The variable "badfunc" should now be defined as the function we just used
• Make another new document. "badfunc" should still be defined

I am currently using the latest operating system version available (6.2.0.333 as of now).

Thoughts?

My textbook says there is a downloadable program named SDINT and I cannot find it anywhere!

Please help my assignment is due in 3 hours :(

I have an old TI-82 calculator, and I am interested in writing some assembly games for it. However, most of the guides online are 20+ years old and have many broken links and missing pages. I would try to contact the authors of these guides, but I highly doubt that the email addresses they posted are active anymore. Could anyone here point me in the right direction?

I'm trying to run some good old games on my TI84+

I have read that Doors is the new Mirage OS and installed it.
But every game I try to run gives out Error 554. Accroding to the Error code site
this means "Archive is full", but the Error messeage says "Basix Ex Err:prg"
I remember I had a version of Space Invaders running in Mirage OS back in 2011
I also tried Mirage OS but all Space Invader games I download won't even show up there, or
give out this error in Doors CS7. The only tutorials I find are pretty basic and there are no
hints what the error code wants me to do.
Thanks in advance, hope something I wrote makes any sense.

I want to download games on my ti 83 calculator but i dont have a silverlink cable i cant buy one becouse they cost 300$ in poland so i want to make my own. I want to use the ti connect software but i just dont know how to make one, i know some sottering and i have a usb to serial adapter and i think I can make a serial link but i dont know if it will work?

i already have mirageos but i also want to download ion to play more games. When i download the ion zip from ticalc.com i take out the ion 8.xg file and try to copy it onto the calculator but it just shows a error. please help

When I type in an equation for the PMT formula it meets me with a syntax error. I type it just the way that is done in this video but it doesn't work. I have a test soon and i need this formula for it. What can I do to fix this?

Video that I'm following: https://youtu.be/xwcD83sjsig?si=0j2jUs4aIBEbk8uG

include other types of calculators if cheaper, not just texas instrument ones

I have a TI-82 stats wich is very simmilar to ti 83 and i want to install some programs on it but for that i need a cable a "SILVER-LINK" it is hard to get in Poland and shipping from US is very expensive (30$) it is not avaliable on allegro so where do i buy it?

It just keeps getting stuck on this, I have already tried to do the solutions posted on the TI website but I am at a loss, I tried resetting it and to disconnect the battery and connect it again but it still doesn’t work

URGENT!!

I have an unknown limit, m. I am trying to solve m such that

fnInt(arccos(x), x, 0, m) = 0.5

m=0.360. Can my ti 84 plus ce do this? If so, what are the specific commands? I tried using Numeric Solver under math, but the ans is still wrong.

additionally the next part of the question is to solve for another unknown variable, a, such that
fnInt(arccos(x), x, 0.360-a, 0.360+a) = 0.3

the ans is a=0.125. I am trying to find an easier way to just instantly solve this as it would really help me during exams instead of taking time to integrate by parts and substitute. Please let me know if ther eis any solution!

Hey everyone,

The title is pretty self explanatory, but does anyone have any suggestions on where to find software that would be similar to Mathway Algebra Solver? I looked around on ticalc.org and cannot find anything. Maybe I missed something, but if anyone has any good ones please let me know!

This is super urgent!! I have an exam right now and have been trying to figure this out for HOURS. Can someone who understands calculator programming please tell me how to get my TI Connect CE to let me send my program to my calculator? I was finally able to jailbreak my calculator, but need to save my notes on TI Connect CE to my TI-84 Plus CE calculator. However, it keeps saying there's a bad token and I don't know what it could be referring to since it looks fine. I have a MacBook and cannot seem to get my program I desperately need in my calculator like yesterday (which is my own fault but I've been trying to figure out the code and everything for hours now), so please help. I really don't know what to do to fix this. Thank you!

So I got this program and I'm not really sure how to use it. The instructions are simple but I'm stuck on "DATA LIST:" I dunno if someone can test this program and tell me what am I doing wrong:(

Here is the link where i got the program

Hey all, I have a Ti-84 Plus CE-T Python Edition calculator that has stopped charging (the LED is just orange forever whenever you would try to charge it) and it would not turn. Amazon (the marketplace I bought it from) promptly told me they cannot help since the warranty expired a month ago, and any attempts to reach Texas Instruments’ customer helpline in Europe would either result in getting redirected to a non-existent phone number or one that isn’t even formatted correctly. I have sent them a ticket a few days ago but haven’t heard since.

I have tried swapping the battery from my friend’s calculator into mine but that didn’t result in anything. (In fact, mine works just fine in their calculator)

I have noticed there is a bit of bulge on the battery but it should’ve still worked with a working battery… There is no visible damage to it, nor was it ever water damaged, nor could I see any corrosion on the battery pads.

Are there any troubleshooting steps I can take to find the cause of the issue and repair the calculator? I cannot justify spending 175 euros for a calculator (it was 100 when I bought it and I thought that was expensive).

As the title says, is it possible to make a program for the extended euclidean algorithm? Have looked around but can't seem to find anything for the TI-82

Is there a way I can get my nspire cx II to rearrange algebraic expressions? I know how to download files/programs into the calculator if there is one that rearranges algebra out there. Thanks!
