Overview:

Dwarven Centurions are basically prehistoric terminators. Thus they now have a chance to drop their still intact CPUs upon killing them.
These CPUs, besides being valueable, are fully operational pocket calculators. Besides basic operations, they are equipped with functions, memory slots, and more.

To use the calculator, just activate it in your inventory.
Typing "help" opens the help menu where syntax and such are explained.

Requirements:

• SKSE (hard requirement)

Installation:
Can be installed both on a new game or on saved games at any point.

• Recommended: as always, with your favorite mod manager.

• Manual: only at your own responsibility. Extract the contents of the archive to Skyrim/Data.

Compatibility:
It just adds things and doesn't edit anything in its master, so it should be compatible with everything.
However, if another mod reverts or removes the LootDwarvenCenturionSoulGem LeveledItem list, it will stop this mod from dropping calculators.
If due to this (or other problems) you need to fully reset the mod, you can do that easily:
