Spock levels of fascinating from me. I want to learn how to compile a pdp11 emulator on my mac.

Compiling an emulator is quite easy: have a look at simh. It's very portable and should just work out of the box.

Once you've got that working, try installing a 2.11BSD distribution. It's well-documented and came after a lot of the churn in early Unix. After that, I've had great fun playing with RT-11, to the point that I've actually written some small apps on it.

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.

Apparently Yufeng got SIMH to run it: https://www.tuhs.org/pipermail/tuhs/2025-February/031427.htm...
