Hello! I put a few more freshly scanned PDP-15 manuals online.
They are currently stored on my dropbox but I suggest that interested parties store them in a better place. http://www.datormuseum.se/documentation-software/pdp-15-documentation There are manuals for SGEN, PATCH, PIP, DDT, Fortran etc which I didn't found on bitsavers. I plan to scan remaining manuals whenever I get time. If there are some manuals that are more wanted than others I can prioritize them. /Mattis
