Hello, Bob Supnik made a new open-source multi-platform emulator called SIMH. The website is: http://simh.trailing-edge.com There is "software kits" for many platforms supported by SIMH. Unix 7 for PDP-11 is included. They are available here: http://simh.trailing-edge.com/software.html The accompanying documentation is available here: http://simh.trailing-edge.com/pdf/simh_swre.pdf It is very easy to set-up systems with these kits and this documentation. You will be able to run Unix 7 with SIMH soon. I hope to have helped you. I am french too :-) -- David
