Less talk about permacomputing and more programming :)

https://t3x.org

    - T3X0 and a lot more languages from there will compile to Unix, DOS and even CP/M. There's a Tetris clone, some shooter, a Ladder clone, some editor...

    - S9 Scheme has Ncurses and sockets support, it can do a lot, basically all the exercises from Computer Abstractions. If you are good enough at Scheme you might do SICP by reusing the graphics.scm code for (frame)

    - Klong it's an APL/K like language but without odd symbols. It comes with a greats book on statistics.

    - MLite it's a great ML/Haskell-like intro

    - NHM Basic it's more like a toy Basic but it can do a lot with a bit of effort

    - The repos from this guy have nice games such as Scoundrel (portable to subc with a bit

of effort) and vm's like mu808, and Scoundrel can be adapted to S9, T3X0, MLite, NMH Basic on hours.
