For all without a good private library of original manuals the bitsavers.org document archive of historical DEC manuals comes to the rescue. Another good source of original manuals was the former UQ Museum of IT . They are now archived in the www.computer.museum.uq.edu.au folder tree at bitsavers.org and marked with a (UQ).
But be aware that all manuals are under the copyright of DEC, now held by HP.
