All, I have revised my Research Unix Version 6 instructions for 2022, in part to support the change to OpenSSH and also to bring it along into the modern era (I did it on my Monterey instance). I updated the links, cleaned up some lingering issues, and confirmed it working. Please take a look and let me know if you find any issues, misrepresentations, missing pieces, etc. I haven't touch v6 in a while, but it was fun to reminisce. http://decuser.blogspot.com/2022/10/installing-and-using-research-unix.html Regards, Will
