HOWTO: TI-83 Emulator on Linux

When you are trying to show a classroom full of students how to enter a complicated equation into their calculator it is pretty much always best to give an example. In order to do this in an effective manner I like to be able to display the calculator on the projector. Most students today have a TI83/84 model so being able to have an emulator for one of these on my laptop is essential. The following is how I went about getting a TI-83 emulator setup on my Bodhi Linux machine:

First - Download, Compile, and install Tilem

My TI emulator of choice is called "Tilem". It is an open source project and you can download the latest source code here. Extract it's contents and do the:

sudo make install

dance that compiles so much software. If the software doesn't compile for you first try be sure to check the README file and the configure script output - odds are you are simply missing a build dependency. If you can't figure out the issue on your own pastebin the error message and post it in the comments - I'll do my best to lend a hand.

Second - Obtain and use a ROM Image

There are a few different ways to get an image of a TI-ROM. You can dump the ROM off of a physical calculator you own (mildly complicated, check that README file for details on this) or you can hit Google. I found a good TI83 download here.

Next simply launch


and point it to the location of your calculator ROM file. Once you select it your TI emulator should appear on screen:
