[time-nuts] HP 106B quartz frequency standard...the story so far

[Stan Searing]

I uploaded the 106 manual I scanned last week to Didier's web site.
It's about half way down at
http://www.ko4bb.com/cgi-bin/manuals.pl?dir=HP_Agilent .
(It's a pdf and you have to skip over the folders to get to the items that
are in a single pdf.)

Hi Jim,

I'd be happy to see what's up with your 106B.
Could you please email me the manual, or let me know where I can download
it?

Thanks,
Adrian
