Plessey PM-D11/SPC-1 backplane documentation needed

Hi, all, I have a Plessey PM-D11/SPC-1 backplane here, and I'm interested in finding some documentation for it. I looked online, but couldn't find anything? This site: http://www.compsy.de/gebr-vax/repman_verl.htm seems to list one, and does apparently 'rent' documentation, but I'm not sure they're ready to rent something to someone on another continent. (If someone in Europe can assist in dealing with them, I'd be extremely grateful.) I do have a manual for the vaguely similar PM-F11/SPC backplane (which I would be happy to scan promptly if anyone has a need for it; otherwise, it will get scanned when I obtain a round tuit), and that, plus an ohmmeter, would probably allow me to eventually figure out the PM-D11, but I figured I'd look and see if I could save all that work, and put it into something else... :-) Noel
