Windows subsystem for Linux is pretty much the modern version of that. Before it was partially based on openbsd and called windows subsystem for unix. The original was NT posix subsystem and was hastly hacked together to just barely support the standards required by the US government. If I remember right there was zero user facing utilities it only supported compiling posix compatible code.
It’s quite fascinating history. Also Apple just ported unix system V to Macintosh, heavily modified x server, some Macintosh app compatibility, and called it A/UX. Actually apples version of unix was fully featured and seems nicer than system 7 it ran beside.
