mk2s/unixpc-build repository overview

A Docker environment for compiling the AT&T UNIX PC (3B1) kernel — and other native software — using the machine's own toolchain (cc, as, ld, make), run under runupc⁠, a user-mode MC68010 syscall emulator. Note: the emulator is new and not proven. While it may produce a kernel; use at your own risk.

You edit the kernel source on your host with your normal editor. The container compiles it in emulation. Build products land right back in your source directory on the host. No cross-compiler to configure, no full-system emulator to boot.
