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.

I've been messing around with RSX-11M myself! I find these early OSes quite fascinating. So far I've set up DECNet with another emulator running VMS, installed a TCP stack, and a bunch of compilers.
