I found it a lot of fun to interface with the TI calculators directly using the wonderful ArTICL Arduino library[0]. You can cobble together a link cable to imitate another calculator and hook it up to your microcontroller of choice. I enjoyed making a QWERTY keyboard and news app over WiFi using the tiny ESP-01 (as, coincidentally, @shakna suggested in this thread). 0: https://github.com/KermMartian/ArTICL https://github.com/KermMartian/ArTICL
