How to Upgrade the TI-83 Plus

Save

The Texas Instruments TI-83 Plus has a user-upgradeable operating system. Upgrade your calculator using the Texas Instruments USB cable and free software. The cable comes with the software on a CD, but you can also download it off the Texas Instruments website. The software works on both Mac and Windows computers.

Things You'll Need

  • Texas Instruments Silver USB cable
  • Check the current version of the operating system on the Ti-83 Plus. Press the "2nd" key, then press "Mem," and press "Enter" to select option 1. The version displays on the screen.

  • Download and install the TI Connect software from the Texas Instruments website.

  • Plug the USB cable into an open USB port on your computer. Plug the other end into the TI-83 data port. This is a non-standard USB cable, so you must purchase one from the Texas Instruments website or one of its retail partners.

  • Download the latest version of the TI-83 Plus operating system. Mac OSX users can open the TI Connect application, then drag and drop the file on the calculator icon.

  • Drag and drop the file onto the "TI Connect" icon to upgrade the operating system in your TI-83 in Windows.

Tips & Warnings

  • If the batteries in the TI-83 are low, replace them before you do the upgrade. Four AA batteries are required.
