Edit: I've decided to go with option 2, with normal code editing.

I'm working on some TI-BASIC development tools, with a CLI for converting between txt and 8xp files and writing TI-BASIC programs. I'm coming to a crossroads at where to take the project right now.

I have two options:

1. Modal Token-based Editor

This is easier to make and prevents any unknown bytes from entering the calculator.

Two modes: Normal and Add

The 8xp is converted to commands, and then displayed. In Normal mode the arrow keys navigate through the file.

Typing switches the mode of the editor to Add. The typed text is added to a buffer, the arrow keys allow navigation through the commands, like on the calculator. Pressing escape clears the buffer and places you in Normal mode.

When a match of text in the buffer to a TI-BASIC command, using a similarity algorithm, it is displayed. The up and down arrow keys allow you to select which command you want to add. Left and right allow you to move the cursor in the buffer.

2. Normal text editor

This is more difficult as I have to make a greedy lexer for the data.

It would be, in my opinion, easier to use, as you just write code like any other language.

What do you guys think?

Hello everyone! I got my hands on the TI-84 Evo yesterday and, having a Linux desktop, quickly became frustrated about the new in-browser TI Connect Evo. Even if using Google Chrome, Texas Instruments has restricted access to TI Connect Evo to specifically Windows, macOS, and ChromeOS devices. While I was able to get it running after jumping through some hoops, this prompted the idea to develop an open-source alternative.

Planned features:

• Capture screen (already implemented)

• Transfer files to and from the calculator

• Perform a software update

• Exit Test Mode

Supported platforms:

• Windows, macOS, and Linux

Release date:

• May 15, 2026

Current status:

I have successfully reverse engineered the USB communications protocol used by TI Connect Evo and have written a PoC Python script that captures the calculator's screen by simulating the packets sent by TI Connect Evo and parsing the calculator's response. This will be expanded soon to include all functionality currently in TI Connect Evo, and will feature a much nicer Tkinter GUI.

I will post here as I have more updates to share. Thank you!

Is there a way I can get ChatGPT/ web browsers on my calculator with only needing to download stuff to my calculator and not like saudering stuff onto it? I go on YouTube but all the tutorials are out dated. My buddy at work bet me that I can’t and if I can’t I owe him 500$ so I need help desperately. After im done with the calculator im just gonna throw it out I don’t even need ChatGPT for anything. Any tips or videos or discord links will help.

^(I accidentally updated to 5.8.5, when will there be a new jailbreak. as the JB is made by unpaid volunteers, what would the timeframe be for a artiface patch or is there a way to downgrade (btw i have a ti 84 plus ce python - 1025010788 L-0223AA))

^(ps.)

^(can you get games on the ti 84 evo or is that never possible)

Please read this before performing ANY OS upgrades.

TI Patches ArTIfiCE jailbreak

A couple weeks ago, TI released TI-OS 5.8.5 for the TI 84 Plus CE and the TI-84 Plus CE Python. From experience, this is an unpresidented move by TI, as they typically only patch jailbreaks if a security flaw is discovered (There is no flaw in this case).

Why did TI do this?

Honestly? I'm not sure. My best guess is with finals coming up, they wanted to stick to their "no distractions" tagline.

I upgraded to 5.8.5! What should I do?

There is really nothing you can do. Once you upgrade, your locked in. Your options are really:

-wait for a new jailbreak (could take months or even years)

- Use TI-BASIC for now, or use Python if your calc supports it

- Trade with someone running an older OS if they don't care about ASM/C

- If you bought your calc recently, you might be able to return it, get your money back, and buy a new one (most of them still come with 5.8.2)

If your calc is NOT on 5.8.5:

No action is needed. Just leave the OS alone and don't update.

The good news:

With the release of the TI-84 Evo, this game of cat and mouse is over as the cat has basically moved to a new house.

I tragically need Pineapple CAS for a math test next week but I accidentally updated my calculator to 5.8.5. What can I do? Would really appreciate some help.

Btw, I am not cheating. We are allowed to use CAS on calculators. Thank you!

So, this is one thing I’m wondering, in the Ti-84 Evo’s trailer it stated that it had a 3x better processor than the previous CE. Will this give the Evo the capabilities to finally run GameBoy Advance games on the Calculator? Seems intriguing
