The TI-89? Or maybe the TI-92? If you (sadly) took math lessons in high school, you must have owned one of these best-selling calculator models in the world.
So, for those who took advantage of their high school to get rid of this cursed (or fawned, for others) object, the Internet Archive site had the good idea to digitize these objects on a dedicated page. Therefore, the calculators can be emulated and are fully functional on your computer.
Functions, derivatives and theorems of all kinds are yours. And if you’re really lost, the Internet Archive team had the good idea to digitize the user manuals as well.
On the other hand, you will not find the arcade games downloaded in it, nor the formulas discreetly engraved by hand in its bowels as a small reminder to better prepare for high school.
Enough to immerse yourself in the past years without worries before studying or working.
