Sorry, the prior note got away from me too quickly. I would like the 5061b
manual. Let me know how you would like to proceed.Jerry

5061B service manual;
10811 oscillator (non-working?) free to good home Hello Time-Nuts people, I
have a 5061B factory service manual, and a 10811 oscillator (missing the bottom
cover and likely non-working) that I would like to give to a good home. I
stumbled across an e-bay listing for a 5016B service manual, and was tempted to
sell mine. And then I found the "time-nuts" group today, and decided finding a
good home for these items was a better choice. If you would like these (I can
separate), send me an email or reply to the note. If there are several
interested in these things, perhaps the community can help me decide the most
worthy home. History of these things: -----------------------In 1984 I was
a new EE graduate working for HP's "PFS" (Precision Frequency Sources)
organization at HP's Santa Clara Division. My first job with HP was to be the
junior member of a two man development team to freshen up the 5016A Cesium
Standard with procurable electronics, as some of the components in the 5061A
were getting obsolete after 10+ years of production. Roberto Montesi was my
fantastic mentor, and the lead of this little team. My job was to redesign
the clock display from TTL logic and LED's, to a 4000 series CMOS and a LCD
display, and to redesign the battery charger board. Both were great projects
for a new engineer, and I was able to dramatically simplify the designs with
modern components. Roberto redesigned the main power supply board, and the
frequency divider module, plus some other stuff. (There is a good story
behind a 10MHz 10811 oscillator, being divided down to 5MHz, and then
multiplied back up to 10MHz before being presented to the customer on the front
pannel. ) One of jobs on the 5061B program was to update the service manual.
I was the engineering editor working with the service manual team to update all
the text and schematics, and text for the whole manual. The 5016A manual was
about 1/3 yellow "change sheets" from all the production changes over the
years, and needed a clean reset. The manual I'm giving away is my personal
copy that I've been storing for 30+ years. The 10811 oscillator was
manufactured by the same department as the 5061B. This one is a cast off I
picked up some where and put in my archives box 30 years ago. In 1993 I left
Santa Clara division for the HP Inkjet Printer organization in Vancouver WA,
where I've worked for the last 25 years. I'm currently living in Singapore,
still developing inkjet printers, and will be home for the holidays in a couple
of weeks, and able to mail the objects then. If you read this far, and found
this interesting, I could try to drag up some more memories of the HP PFS days
from the late 1980s. Hugh
