This repository contains the OpenKeyboard031 sources for the Xbox360 Chatpad's processor (PIC16F883)
These files were obtained while looking through a mailing list archive from 2008. They appear to be the only surviving copy of this project.
The OpenKeyboard031 folder can be found in Ben Heck's video on the video titled "Build a Retro Computer: BASIC 80's Pocket Computer"
I'm currently in the process of hacking my own chatpads and therefore the code here hasn't been tested yet.
Feel free to open an issue if anything comes up
