On Saturday, a YouTube creator called ChromaLock published a video detailing how he modified a Texas Instruments TI-84 graphing calculator to connect to the internet and access OpenAI's ChatGPT ...

They used the TI-84's link port — typically used to transfer educational programs between calculators — to get internet access and a direct line to ChatGPT.

It’s step-by-step instructions on how to install games onto your TI-84 or TI-84 Plus Silver Edition calculator.

The bestselling TI-84 Plus graphing calculator generally retails for between $90 and $120, which hasn't changed since its 2004 debut.

TI says that the new calculator builds on the success of the color screen TI-84 Plus C Silver Edition calculator using a similar thin, high-resolution color screen.

First, download the program from the provided link. Then, connect your TI-84 calculator to your computer using a USB cable. Use the TI Connect software to transfer the game file to your calculator.

The TI-84+ C Silver performs the usual graphing functions, and a user at the Cemetech calculator forums, where the device first showed up, reports that not much has changed.
