There’s always MiniUnix.    https://www.tuhs.org/Archive/Distributions/USDL/Mini-Unix/ <https://www.tuhs.org/Archive/Distributions/USDL/Mini-Unix/>

We ran that on our MMU-less PDP-11/20s and 11/40 before the LSI-11 was even introduced.
It lacks obviously memory protection, traditional UNIX pipes (they’re simulated by the shell if I recall), and preemptive scheduling.
