trying to be on here more often (again lol)

Back on my BS with my project to make a portable version of Unix V6 (from 1975) with a self-hosted pre-K&R C compiler, that could be released on anything that can at least simulate the memory model

Gonna start on a custom VM written in #Rust, but then port to the #C64 and probably also #ALtair8800!!

You can check out the progress on the kernel branch here: https://codeberg.org/popeyeotaku/popix/src/branch/kernel

Right now the compiler's almost done, with a bootstrapper compiler written in Rust. I'm about to start booting and bugfixing the kernel as soon as I extend the VM a tad

Still gotta gut the kernel by another several K, and write self-hosted assembler/linker package, and port userland. Also gonna write a custom YACC that uses less RAM

but it's coming along swimmingly!!!

A highly-portable implementation of 1975's Research Unix Sixth Edition (aka Unix V6), with minimal system requirements.

@PopeyeOtaku Holy moly! This is such a great idea.

@psf absolukely a PC-XT class port will be in the cards too

As long as ur just doing text processing, everything will be portable between these platforms

The self-hosted compiler uses a dirt-simple IR backend that's easy to port to things, and to use as a target for new compilers
