here’s a link from maurizio that has instructions for overclocking your favorite ti graphing calculator. a simple swap of a capacitor and you can get your homework finished double speed. add a switch and you can convert back to normal speed for playing games.
This has been something fun to do in the TI Calc community since at least 1998.
Heads up, though- battery life will dramatically suffer if you’re overclocking (duh!). Be sure to keep a spare set if you overclock your TI and then sit for the SAT or you may find that Very Bad Things ™ will happen.

Awesome hack. Thanks. Truly geeky.
Yep, this is truely an old hack. Getting the soldering right and getting the switch to fit were a little troublesome, but, given that I was working with a ham-fisted soldering iron and I was just barely a teenager at the time, well, it worked out quite well. It made ‘Marble’ truely interesting on the TI85.
Did this to my TI-83, worked okay for some things. Actually it wasn’t my TI, it was my high school’s. :) Anyway it worked, but I got some distortion on the screen when it was on. My HS math teacher hated me for installing games on everybody’s calculator.
will this work similarily and safely on a ti-83?
unforunately…this can make a bad calculator. I had one melt the processor when I overclocked it. It ran awesome…then died.
can it work for a ti-83+ ?
great
great

this works, but I just removed the cap alltogether. No side effects except it was faster.
Of course I never even came close to using the full capacity of the calculator, but I could add and subtract at lightspeed!
Tetris was tough though.
