[time-nuts] Seeking Toyocom or NDK through hole oscillator information
Seeking Toyocom or NDK through hole oscillator information Hello again to the group, I'm looking for a Data Sheet or information that would provide the connection information for a (Epson) Toyocom TCO-519 or NDK PIA3003A Oscillator module, both are through hole mounting. Both appear to be a reasonably conventional, but now a discontinued through-hole part, but I'm unable to find any same or similar data sheet information that would tell me how to use connect them. Both are 16.368 MHz Appearance wise, they are both an approx 1 inch square, 3/8" high, silver metal covered oscillator module. Five through hole mounting connection leads on the bottom, one in each corner, the fifth lead is centered along the side between two corners. A data sheet or even just the generic connection information with an idea of what each pin does would be wonderful. A few of these arrived in a parts donation box hand labeled "Trimble Development". Possibly something Trimble significant with the 16.368 MHz frequency that I'm not yet aware of... if anyone would care to speculate, please do.

Re: [time-nuts] Spectracom 8140T Line Tap Schematic

That method of "encapsulation" was used by a number of Rochester electronics firms of the era. It was developed by a good friend of mine with whom I worked at another firm about a decade before Spectracom was founded, and was introduced at Spectracom when he moved there. It's hilarious now, looking at the crude PC layouts, the PC cards that look like they were separated with hatchets (in reality, they used heavy-duty, office-type guillotine paper cutters), and the "definitely not near mil-spec" hand soldering job using at least 5x the optimum amount of solder. Spectracom didn't even have a dip-soldering operation, much less a wave-soldering system. It was a much, much simpler time, one rung up the ladder from hippies in a basement Charles ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
[time-nuts] Raw phase data of super-5065
Saw the plot in the June 12 post. Pretty much limited by the 3816 up to 10K Seconds. Would be interesting to see a long plot of the two 5065 against each other!

[time-nuts] Reminder -- upcoming list changes
Just a reminder that starting this Friday, June 15, postings to the febo.com mailing lists will need to use the new addresses -- @lists.febo.com instead of @febo.com. You can start using the new addresses now. The list server will be shut down for an hour or two on Friday to make the configuration change. The transition to the new server will happen over the June 30 weekend -- the server will be shut down on Saturday, June 30, so the data can be moved to the new provider. The lists should be back up no later than Tuesday, July 3. By the way, if it wasn't clear in my other message -- after the move, the lists will still operate just as they did before, with the same administrators and moderators.
