Hi Jim: There was a Burroughs mainframe available free for the taking last November or December. Unfortunately it was in Australia. I corresponded with the fellow on behalf of a new cold-war era museum that is under development near Ottawa Ontario. You might contact the folks at http://www.diefenbunker.ca/indexe.htm and see if they had any luck with the Burroughs machine after I put them in touch with the fellow in Australia. They are looking for a 50-60s vintage Burroughs mainframe to install in the machine room of the bunker. I offered to coordinate shipping but did not hear back from either party afterwards. Perhaps the Australian machine was the incorrect model for them - they might be able to connect you with him to see if what he has meets your needs. Good luck, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
