It seems reasonable, cause along with them and the forty something pdp8 
floppies I also got over
50 pdp11 floppies. Unfortunately I don't have any experience with pdp11s 
but this could be a starting point.
Also got a few dozend handbooks (most of them for various pdp11s).  So 
enough to read in days to come.

Just started archiving the pdp8 floppies, will dig my way through and 
see if I also can read the
pdp11 and/or the Racal-Redac floppies.

Thanks for the hint
