Bill, I think the unit you found pictures of may have been a factory throwout. It has no oscillator (would have been the E1938A), and no serial plate or HP sticker, and no calibration certificate.

Re: [time-nuts] time-nuts Digest, Vol 34, Issue 9
T&Fers, Re the HP Z3815A, let me answer a few questions: 1. Most of the few Z3815A units I know about use the HP E1938A oscillator, and that's what plugs into the connector that's clearly visible on one of Bill's photos. At least one example has an adaptor labelled Symmetricom, carrying a Milliren oscillator. The GPS module is by Furuno, and speaks NMEA. The Z3815A speaks SCPI, a closely related dialect to the Z3801A, and works fine with SATSTAT. 2. The backplane is not the problem you guys are imagining. You can easily pick signals off it, since the socket is 2.54mm pitch in both directions (ordinary PCB strip pins work fine). The 19.6608, 4.096 and 1.544MHz signals are available there in 'pseudo-ECL' form, although little is known about other signals. The 10MHz signal is available from three (unknown type) coax connections in the white block at the top end, but the back of this connector is easily accessible with the back cover off. The GPS antenna connects here as well. 3. Inside, there are easily discovered SMB connections with 1PPS, 10MHz etc. 4. Power is applied to the backplane, but it's also easily applied internally as there is a socket footprint on the board. It's easy to extend this to a socket on the back panel. The unit requires 20 - 56V at about 25W, and runs fairly warm without ventilation assistance. And most important of all: NO, THERE ISN'T A GREAT HORDE OF THESE THINGS AVAILABLE! The few that have surfaced down here have been distributed locally. Don't expect them to be offered on the open market. 73, Murray ZL1BPU ___ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
Re: [time-nuts] NTP Synchronised Nixie Tube Clock
Hello, as I do not have problems with this strange lange, I hope I can help finding the answer ;-) According the description, not having started with a ready overall design the developper Friedhelm Bruegmann did work 7 years on it! He did start, because he had the idea to bring all his collected valves into practical use after a long period of collection. A lot of appearing technical problems had to be solved then. Therefore it was not possible to have a clear idea about the power needed for this project, which finally gave him some headaches. Though theoretically possible to avoid all semiconductors totally, the transformers of choice turned out to be too small. As there are already 103 vacuum tubes in use, just the heater current levelled up to 39A! But, as at the time of digital breakthrough semiconducter diodes were already in mixed use with VTs, Friedhelm did not see a breach of style to use SC-diodes. He applied 4xBY227, 66xBA157, 72x1N4148. All these parts are clearly shown in the diagrams and mentioned in the description. I stopped thinking about the bigger size of chassis he would have needed. Anyway, a outstanding development!

It seems like your browser does not handle Javascript the way it's intended. The way it's supposed to work: the Javascript instructs the browser to fetch the document's time stamp and render it on the page.

Actually, it appears to be a misconfiguration of your web site. It is not returning Last-Modified: to an HTTP/1.1 request. Both a local site and a different remote site I tested work fine. On your site, Opera 9.2 always returns January 1, 1970 GMT. IE7 and Firefox 2.0 always return the current time (the timestamp will change each time the page is reloaded).

Re: [time-nuts] NTP Synchronised Nixie Tube Clock
Well, that is even more interesting! You are correct of course, I had not noticed. I use a commercial ISP and I will open a service ticket. I developed the original format of the web site (including the little bit of Javascript) on a local Linux box a number of moons ago and transfered it to a commercial ISP that shall remain nameless. At the time, that was working (maybe the only thing that was working with that ISP...) When I got tired of that ISP and switched to my current ISP (Globat) 3 or 4 years ago, I do not remember checking the time stamps. My fault :-( I do not know how long it's been like that. Thanks for pointing that out. Didier KO4BB PS: just for grins, I copied the Clock/index.html page to my cox.net webspace (which I do not normally use) and it returns the right date, so the Javascript at least is still OK. http://members.cox.net/didier/ Mike S wrote: > At 07:22 PM 5/8/2007, Didier Juges wrote... > >> The page uses Javascript to instruct the browser to fetch the document >> >> updated time stamp.

Re: [time-nuts] NTP Synchronised Nixie Tube Clock
I have an interesting 1MHz crystal that I got a number of years ago when I was at the HP Santa Clara Division (Hertz Castle is what they called the place). It is an HP P/N 5080-0031 1MHz crystal, gold plated, and in a glass vacuum tube. I'll have to take a picture of it and post it... It's really quite pretty!
