A number of you have suggested that the 5061B manual to bescanned and shared more broadly.  

I’ll look into doing that when I am in the USA  in a couple of weeks.   Could someone providea place to  

post the scanned PDF files where many can access them?

 

I’ll likely give the original 5061B manuals to TomVan Baak, the originator of the Time-Nuts.

 

 

On the 10811 oscillator; many are interested asking forit.  I’ll have to come up with a way ofchoosing

who to send it too.   I may have oversold this thing: It is probably less complete than many are hoping.

Is there a way to post pictures to this mailing list sopeople can see what it is?

 

Finally, my apologies for the formatting of my messages, andprobably not posting correctly.  Thetime-nuts

email system seems to eat the carriage  returns from my Yahoo.mail account.    Maybe this one will be better.

 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.
