Since I work hard to let people know about the archives of PDP-11 software already out there on the net and on CD-ROM, I'd be interested in knowing where (exactly!) you looked and how you came to the conclusion that there was a vacuum. Nope, it'll run on the real deal too. You have to be a bit careful: most of the old Unices there think they're running on a Unibus machine, so if you run them on a Q-bus machine some funny things will happen if you go above 256K due to the lack of a Unibus map. (This applies to the simulator, too, since it emulates a 11/53!) I think you're confusing "it can't" with "you aren't supposed to". The hobbyist license that Supnik worked out only allows you to run the software under his (or another DEC) emulator. There's talk about a very much more permissive license deal coming up, but the talk is - so far - just talk, and it could get nixed by the lawyers simply taking inaction on it. If and when it does turn solid, you can bet that this mailing list will be one of the first places you hear about it. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
