[time-nuts] 1970's flashback

[Dave Brown]

Thanks for these, Joe.
 The photo with the sign 'set your watch' is especially interesting for me 
as it shows a pair of old clock displays the same as one I have here.  These 
are the two  digital displays that are showing the same digits. There's part 
of a third one the same on the extreme left but the display on that one is 
not visible in the photo.  My clock has a different mechanical dial on the 
ten turn pot at the extreme right of the front panel- otherwise the unit I 
have here  looks identical to those in the photograph.
 I have never been able to track down any info on this unit. Mine came from 
a US military installation here in NZ (Black Birch) that has long since been 
shut down. It's certainly old technology- RCA 'numitron' displays and mostly 
TTL circuitry. I've had it running here continuously now for about six years 
driven from an HP 5245M timebase - the clock has never missed a beat. 
(recent quakes excepted )  Also. one of the newspaper cuttings in that 
collection you posted mentions the flying clock being down here in NZ to 
visit Mount John, a magnificent observatory site in South Canterbury.  These 
days it's a well known astronomical observatory run as part of Canterbury 
University Physics Department.
