According to the chart at
http://www.columbia.edu/acis/history/sorter.html the 082 ran at 650 CPM
while it was the 083 that ran at 1000. I think I was confusing them and
that by the early 60s it was more 083's that I saw. This old non-ECC
wetware is tricky. ;-) Some customers were very slow to upgrade though,
and I definitely remember some 082's and even 080's in that time frame
complete with gears running in moly grease - what a mess to repair if
you had to open that up. I don't believe I ever saw any of the fancy
options either, certainly not the 10-column brush and plugboard option.
I believe only a total items counter was all I ever saw as well, and I
think most customers had that one counter.

I never used an 084, either. Vacuum? photocell??
2000 CPM??? WOW!
Must have been 082s. Were there any earlier minimal models without
counters? ISTR some elation over upgrade.
I went to the bitsavers document on the 082, 083 and 084 sorters.
The counter was an option for all three--it could count total read as
well as the number in each pocket. There were some other fancy
options, including alpha sort and a 10-column brush with a mini
plugboard for the 082 and 083 to do all manner of fancy combination
sorts. I never saw any of the esoteric options.
The 084 had a 3600-card feed hopper. That means that the beast would
empty it in less than 2 minutes! The operating notes state that you
didn't need to "joggle" the cards (another IBM term) on the 084 as it
was "self-joggling".
