From the project
This TIPI board is for use with danwerner21 (https://github.com/danwerner21/TI99_22.git) TI99-22 project
This projct born to integrate the ElectricLab & Jedimatt42 TIPI board in the new TI99/4A version by Dan Werner. I like so much this project and adding TIPI features without external box or usin PEB seems to me a great idea. Maybe it's not but I like it.
Attribution This board was derrived from works by, uses design elements from, or contains sofware writen by the following:
