Medley, open source emulator for Xerox Interlisp-D machines: https://github.com/Interlisp/medley

Your concept looks nice, it reminds me a bit of the Lisperati: 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

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

Finally, bare-metal Smalltalk is available in my crosstalk system: https://github.com/michaelengel/crosstalk

Of course, Lisp and Smalltalk can also run hosted under Linux, e.g. using Squeak (https://squeak.org), Pharo (https://pharo.org) or InterLisp (https://github.com/Interlisp/medley).

Or - a crazy idea - build an emacs-only machine. That would be fun! :)

Interlisp for some ideas on supporting rapid prototyping and a historical perspective.

Of historical interest was Interlisp-D as a system that did structure editing and version management. it was at the beginning of time so getting it to work again as a practical development environment is a lot of work.

It uses some JSON OT code I wrote, which is without a doubt the most complex code I've ever written in my career: https://github.com/ottypes/json1

> Even if we get the OT part right, it’d be huge effort to port this to support other semantic structures with different set of ops

Its very doable, and its been done. Eg, in json1[1] we have support for lots of tree operations on a set of data stored as a JSON tree:

- Insert / delete in lists

- Move (reparent) any object in the tree

- Embedded edits (so if you have a custom type inside a field and define your own operations)

This is all very general purpose. You don't need to do reinvent any of this per application.
