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.
