@mrmprog, the CX has the same dock connector as the original.....
Cool stuff! I was actually looking for a lab station on ebay for cheap, just to get the port
In the meantime, I have a header soldered to my extra 84+ pad. I want to use those 2 GPIO pins from the Touchpad connection
Speaking of GPIO pins, the nspire is full of them. SD cards can somewhat simply be run through them as well
so no more 32 MB limit!
