I have completed my transcription of what I felt would be the most salient entries and information in those entries of the PDP-11/45 DEC-O-Logs.
Curiously, there were no entries at all for the KB11-D. The transcripts are available on my Google Drive at https://drive.google.com/open?id=0B2v4WRwISEQRWWFFdVpCZWFTZEU under pdf/dec/fieldService/dec-o-log Of course, they won't be 100% accurate, but I did take special care to note areas where I had trouble making stuff out, and over signal names and FCO cuts/adds where available. Note/offer: If someone has a good way to scan fiche, I could send (one at a time) my JAN86 and JUL86 fiche sets (9 fiche) off to that someone to scan/print.
