How do I update my TI-83 operating system?

First, check the version of the operating system using this information.

If your system doesn’t have the latest version, you can transfer a new  operating system to the TI83 via a PC or Mac or from another TI83 using info starting on p633 of the manual.

You will need a TI Graph Link cable to make the transfer via a computer.

Make sure the cable is compatible with the TI83.

Check here for places that carry that cable.

A knowledgeable salesman at London Drugs in Burnaby said the store no longer carries the cable. (The TI-83 is an older model but works just fine.)

If you know someone whose TI83 has the latest version, you may bring that calculator to one of my tutoring sessions and I can update using a calculator-to-calculator cable.

I have a TI-84 Plus, which cannot update the TI-83 calculator.

No worries. Your TI-83 is fine for the SAT, even if you don’t have the latest operating system.

But if it’s possible to update it, you should.
