Dave -- I'll check on that hp display clock. I have a couple like it, with Nixie tubes, but without with the ten-turn pot on the right. Interesting, that time/stepper unit does not appear in hp's own frequency standards lab: http://leapsecond.com/history/Benchmark.htm All -- For those of you who are interested in 70's era of flying atomic clocks do read the original reports of the various world-wide campaigns to align (coordinate) each nation's time standard. We take this all for granted now that GPS is everywhere, but in those years it was a real chore to keep, compare, and carry time.
