There is a rare HP clock on ebay for the collectors among us. I am to old. RARE HP H20 115BR FREQUENCY DIVIDER & DIGITAL CLOCK STANDARD VINTAGE TEST Bert Kehren

I saw that. Is it really rare or just hype by the luster?

Hi Rare is indeed a relative term. I would certainly call it rare, but others might not. You likely would be the only person on your block who has one :) In the picture of the innards you can see a number of fine old wet slug tantalum capacitors. One even appears to have goo leaking out of it. I’d plan on having a lot of fun tracking down this or that part to get it working reliably. > On Oct 3, 2016, at 10:27 AM, Jeremy Nichols <jn6wfo@gmail.com> wrote: > > I saw that.

Also notice the missing something on the far right that may have been some xtal or something. I went to look for a manual to see what it was. No luck though the manual may be out there. I would say its rare, but the price is going to most likely go up because it is a bid. Great winter project but not worth a lot of $ to me at least. Good luck to whoever gets it.

Since you force-feed it 100 KC at the back, no crystal would be needed.

According to my -hp- catalogs it was available only in rack-mount form, not in a cabinet. That suggests it was being marketed to a specific small group so it may indeed have been manufactured in small quantities.

My speculation on the xtal. So the question is what is the empty box on the right that looks like paper is stuck in it. Not that any of this matters as I am not a bidder. It may just add additional challenge for whoever gets it.

There is a fist sized bag of silica gel sitting in an open from the top aluminum box. Most units also have a little 24V Nicad pack. -Chuck Harris paul swed wrote: > My speculation on the xtal.
