Hello everybody !!
I am new in the raspberry pi's world, And I would like to "add" my raspberry pi in my TI-89 calculator, for get more fonctionalities like WIFI (with a usb dongle) or programming,
So I have a lot of programming knowledge but not in electricity (soldering)
I would like some advices to start this adventure 
Is the TI-89 titanium screen is compatible with the rasp ?
thank's !!
