They're are a lot of different versions of Unix out there, with comments, for many machines. If you want simple, there is Unix V0 for the PDP7.

Also, the beauty of running a simulator is that hardware resources are not as much of a problem so I more to fill in the gaps for the stuff I am unsure of. My personal assembly "bible " covers some systems programming but not all. I will have to share the title of the book when I am near it. It is available on Amazon. What my plans are is to make a simple OS with a dual command set using both the RT-11 command line interface and RSX style DCL. Just something fun to play with....

I would like preferably v5.3. I have an idea for project to teach my self rudimentary OS design and I would like to use RT-11 as an example since PDP-11 assembly is the only assembly I know and I am already comfortable with RT-11. Unless I'm confused, RT-11 already comes with some sources, but they are stripped of comments. Also, as an OS, it is rather rudimentary. And the code is sometimes not that easy to follow, since they have used a lot of tricks to squeeze the most functionality with the minimal amount of memory use.
