I am just starting to go through the documentation and found some PDP-1 stuff. I have updated my web page to show pictures of some of the PDP-4 paper tapes and list most of the DECUS -8 tapes. I still have a long way to go as I still have to list all the PDP-1,PDP-4,PDP-5,PDP-8,PDP-9,PDP-15 software,docs and paper tapes I have but have a look. Some really cool finds so far: IBM 360 to PDP-9 Interface manual (theory, manual, schematics) Applications in Physics (PDP-1 and PDP-4) Atomic Energy Canada - uses for PDP-1 Macro-9 source code Focal-1968 source code DECUSCOPES and Decus year end stuff (1965,66,67) (will have some docs online soon) http://www.pdp8.com/ (click on the paper tape picture). PDP-8/s update: The oscilloscope and light pen were installed with success. Will have pictures online soon showing the 8/s draw pictures/letters on the scope. I also have a couple of video games I'll take movies of when I get time.
