Installing and Using Research Unix Version 7 in the SIMH PDP-11/45 and 11/70 Emulators 2.1
It covers building a working v7 instance from tape files that will run on the SimH emulator. First, the reader will be led through the restoration of a pristine v7 instance from tape to disk. Next, the reader will be led through adding a regular user, making the system multi-user capable. Then, the reader will be shown how to make the system multi-session cable allowing multiple simultaneous sessions. Finally, the system will be put to use with hello world, DMR style, and the learn system will be enabled.

Vim User Manual in txt and ps and pdf us-letter
This note describes how to create a pdf (and ps, and txt) version of the latest Vim documentation. I got sick of trying to find a useable and current pdf on the web, so I just figured out how to do it from source and am posting the howto for others who might come after.
