I don't know about 60Hz timebases for older UNIX systems, but I do
remember low end frequency counters being offered with mains derived
timebases - I remember them as a catalog item, I never saw one!
I think they were offered by Systron Donner and this was probably back in
the '60's. They even did a 50Hz option - it must have been a real
time-nuts guessing-stick!
