Your concept looks nice, it reminds me a bit of the Lisperati: https://www.hackster.io/news/the-lisperati1000-is-a-cyberdeck-terminal-dedicated-to-lisp-programming-bb564f2ffcff https://www.hackster.io/news/the-lisperati1000-is-a-cyberdec... So, did you consider Lisp or maybe Smalltalk? Plan 9 or Inferno might also be options. Plan 9 comes in different variants, the "classic" one (with a Raspberry Pi port by Richard Miller) or 9front, an Inferno porting tutorial can be found at https://github.com/yshurik/inferno-rpi https://github.com/yshurik/inferno-rpi Lisp and Smalltalk can run with or without Linux underneath, e.g. on the Raspberry Pi. Bare-metal Lisp is available with interim: http://interim-os.com http://interim-os.com Finally, bare-metal Smalltalk is available in my crosstalk system: https://github.com/michaelengel/crosstalk https://github.com/michaelengel/crosstalk Of course, Lisp and Smalltalk can also run hosted under Linux, e.g. using Squeak (https://squeak.org https://squeak.org), Pharo (https://pharo.org https://pharo.org) or InterLisp (https://github.com/Interlisp/medley https://github.com/Interlisp/medley). Or - a crazy idea - build an emacs-only machine. That would be fun! :)
