Just to keep it short, I am trying to implement a project for the TI-84. It is a hardware modification that utilizes an ATtiny85 as well an RN-42 module. I guess it shouldn't be hard to implement, but my problem is that I don't understand the schematics. This is a picture of it:

Specifically, I don't understand where the "calc 3.3V" wire is supposed to go on the calculator and I have no clue what it means by "TILP port" or where the 3 wires for that one is supposed to go.

If someone who understands this can help me out, I'd gladly pay you for your time via PayPal.
The 3.3V line can be connected to the calc's battery's positive side. The "TILP port" is the round 2.5mm link port on the top of the calculator. You'll want to connect the line that's connected to the ring connector of the port to PB3, and the line connected to the tip connector of the port to PB4.

EDIT: I've also found this article, which has pictures.

Thank you! That really helps. I kind of feel stupid now not realizing where that port was, but I think it would've been better if the author had labeled it as the I/O port Laughing

Just a quick question regarding connecting the 3.3v line to the battery, is the part that you are referring to?
