! Unix v1

! Unix v1 was an operating system for the DEC PDP-11 computer. It was developed by Bell Labs. Sadly, we do not have a complete copy of Unix v1, but we do have a copy with v1 kernel and v2 userland, which we can run on SIMH.

Manuals

You can download the ! Unix v1 manual from here:

Since the copy we have has v2 userland, you will be interested in ! Unix v2 manual as well:

Reading the volume 2A and 2B of ! Unix v7 manual is also helpful. They contain many short tutorials which will be helpful in learning how to use Unix. While the manual is for v7, most of the information included there applies to every version of Unix.
