Yeah, I've been looking at those TI calculators for a few years, hoping to dabble in some Z80 assembly programming for nostalgia. I've also been eyeing their TI-92, 92II, 92Plus, and Voyage 200 series of calculators. They use the 68000 processor and have qwerty keyboards. It looks like there is a C compiler for it (http://tigcc.ticalc.org/ http://tigcc.ticalc.org/), so it ought to be possible to do some interesting things, like this Fuzix OS, or a FORTH, LISP or Lua interpreter, or a terminal program over a serial link to a battery-powered ESP8266/ESP32 to the internet over WiFi.

The 68k calculators are indeed delightful machines. You've found TIGCC - you should also be aware of GCC4TI, a fork of TIGCC due to the original maintainer not accepting contributions, and GTC-IDE which is an independent (non-gcc) C compiler that runs on the calculators themselves (although the frequent memory leaks render the development loop tedious - no memory protection means leaked memory is gone for good until you "reboot"). There is a mature independent OS called PedroM, and someone even made some progress porting 4.4BSD (PunixOS).
