[time-nuts] NTP Synchronised Nixie Tube Clock

I have an interesting 1MHz crystal that I got a number of years ago when I was
at the HP Santa Clara Division (Hertz Castle is what they called the place).  
It is an HP P/N 5080-0031 1MHz crystal, gold plated, and in a glass vacuum tube.
I'll have to take a picture of it and post it... It's really quite pretty!

I think all the old hp 100-series frequency standards were
tube based. Even the 100 kc crystal was mounted inside a
conventional vacuum tube. The old GR quartz standards had
tubes: http://www.leapsecond.com/museum/gr1103a/
So these would make a nice companion to that all tube nixie
tube clock.

The model hp 101A was hp's first "transistorized" standard;
after that came the 103 104 106 107 105 105-44 108-11
