From the link:
> It's somewhat picky about the environment. So far, aap's PDP-11/20 emulator (https://github.com/aap/pdp11) is the only one capable of booting the kernel. SIMH and Ersatz-11 both hang before reaching the login prompt. This makes installation from the s1/s2 tapes difficult, as aap's emulator does not support the TC11. The intended installation process involves booting from s1 and restoring files from s2.
good luck though. my emulator is not particularly user friendly, as in, it has no user interface. i recommend simh (although perhaps not for this thing in particular).
Apparently Yufeng got SIMH to run it: https://www.tuhs.org/pipermail/tuhs/2025-February/031427.htm...
