         | 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.

           | 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.

       | first time I see people use 'ed' for work!!!

       | I wonder who else has to deal with ed also... recently I had to
       | connect to an ancient system where vi was not available, I had to
       | write my own editor, so whoever needs an editor for an ancient
       | system, ping me (it is not too fancy).

       | amazing work by the creators of this software and by the
       | researchers, you have my full respect guys. those are the real
       | engineers!
