So, I've never thought of the 11/70 as being "that rare", but "at least 25"
still sounds to me as being fairly uncommon as PDP-11's go?
How (relatively) common are the remaining early 11's these days? With some
lumping, and ignoring the F11/J11-based ones, in these categories: 20/15;
10/05; 40/35; 45; 50; 55; 60; 70; 34/04; 44? The last two I'm thinking are
still quite common; really no idea about the others ... although the number
of remaining 11/60's seems to be in the bare-handful category. 50's and
55's might be similarly low?
