I agree. If you exclude F-11 and LSI-11 Qbus machines (pre-BA23), the
most common PDP-11 systems in my experience have been 11/34s followed
by 11/24s.

I would class the /S as rare, especially since I have examples of just
about every other model (missing an /S an /f and an /m, and VT-78 if
you count that). I at least have an example of each technological
variety (i.e., an /e, but no /f, etc.)
I wish I could have gotten the racks of -8/ms from the Ohio State Vet
Clinic - a buddy of mine used them (with Tek graphic tubes and printers)
with a mass spec for analyzing horse urine for drugs for the Ohio Racing
Commission. I used to go down and play on his machines when he had the
mass spec torn down for cleaning (removing carbon deposits, mostly).
It was a pair of CPUs, each with a controller for dual-ported Diablo
disks (RK05-like) - he would run the sample with one CPU, store the
results,
then analyze and print the results from the same drives/packs from
the other CPU.
I compiled my first RTS-8 executive on those machines.
