Kolibri OS: fits on a floppy disk, programmed using interrupts

• v86

  153 19,127 9.1 Rust

  x86 PC emulator and x86-to-wasm JIT, running in the browser

Trying it out in https://copy.sh/v86/?profile=kolibrios , it's also clearly a love letter to Windows 95 in particular. That could be an unstated goal here, create a very particular PC experience under very particular constraints. I don't know anything about the creator but it's very possible that this kind of work was actually their career in the 90s.

It's incredible how much work was done. Maybe this should be an internet curiosity like how TempleOS has become, though Terry's personality was a unique factor.

• OberonSystem3

  7 83 6.9 Modula-2

  A cross-platform version of the ETH Oberon System 3 compatible with the Oberon+ compiler and IDE

Even if so, ARM or RISC-V are more attractive architectures in many respects; and there are proof of concepts demonstrating that very lean operating systems with GUIs can be built with high-level languages, even with GC (see e.g. https://github.com/rochus-keller/OberonSystem3/); so writing such a thing in assembler is certainly impressive, but also a cul-de-sac.

• wrench

  4 79 8.1 C++

  practical embedded script interpreter (by jingoro2112)

Doesn't look promissing, sorry. Was looking and looking, but where is the GUI-based OS?

Nowadays we can use LVGL and C++ to write apps, or run script based C code using interpreters like Wrench: https://github.com/jingoro2112/wrench

What I'm missing is an GUI-based OS like Kolibri to launch apps.
