5 Add-ins everyone should have on their Casio FX-9860

Here is my list of the 5 add-ins you should install and never delete:

UTIL V. 1.1

by Mario Roy

With this add-in you can overclock the CPU up to 4x. This is great for BASIC programs, but remember to down-clock it for add-ins! Some add-ins will have glitches with the CPU overclocked that they don’t have with the CPU at normal speed.

Insight 1.5

by SimonLothar

This program has many features that are not developer-specific, such as un-delete, Main Mem View, OSUpdate mode, and a battery meter. I use this almost every day. Keep it where you can get to it easily.

Edit V. 1.5

by Neptune45

This program edits text files on your calculator! You can use it to make lua programs, mlc programs, or even just to make that email you can’t get to the computer long enough to type out.

This is an excellent computer algebra system for the Fx-9860 series. If you are in Calculus (like me), this is a must-have.

3D Grapher

by Vanhoa

This 3D graphing program can handle cylindrical equations, parametric equations, and Z=f(x,y) equations. This program, along with the above, essentially upgrades your calculator to a calculus machine.

BONUS! FX-Lock V. 1.2

You thought I was finished… Ha! I’m never finished. 🙂

This program locks your calculator. Great for keeping younger siblings off your calculator. I put this on my calculator first so it always has the same letter. When I turn it off, I press the letter first!
