[time-nuts] Re: HP105B

[Magnus Danielson]

Hi,

No, not for HP. The HP200A through D products where separate products 
for 8 years, then the 200A and 200B was merged to the 200AB and the 200C 
and 200D merged into 200CD that was running for 37 years, totaling in 45 
years of continuous production. Not bad for a tube-based oscillator. The 
numbers are from the top of my head, but was featured in an HP 
PR-article, where they where proud of this fact, even after breaking out 
Agilent. Someone can probably do the research and correct details, but I 
distinctly recall the 45 total years.

Cheers,
Magnus
