ampliferinstructions.zip393k06-08-05File is not ratedAdding an amplifer into your TI-84
Here are the schematics for adding an amplifer into your calculator. I can not be held liable if you destroy or otherwise make your calculator inoperatable or damage it in any way if you use these instructions. I wrote these for the Ti-84+(SE), but they might be able to be used on other calculator models with the correct modifications.
