You can turn this into a pocket "lisp machine" by following the instructions on http://www.ulisp.com/show?4JAO - although I don't think this can make use of the LoRa interface (yet).

The hardware is cool, but its just a PCB and the edges of the display are vulnerable. I would recommend 3D printing a case to protect it, especially if you are planning to bring it around with you. There are .stp files for one in the official github repo.

You can also do Forth, which does support lora

It's relatively straightforward to build this out with an SPI screen using FabGL, not sure about the keyboard, though FabGL supports ps2.
