I stand corrected. The PDP-11 came onto the market in 1965 (and not 1975 
as I originally thought). It was a radical break with the PDP-8, PDP-9 
and PDP-10 series of DEC  which were based on an octal logic instead of 
hexadecimal logic (PDP-11 and much earlier IBM).
RSTS dates from 1967 and the first non-profit versions of UNIX were 
available in 1969 (of which I then obtained a copy).
Sorry that my memory was 10 years out of date ( well, when you're 
old(er) time flies!).
