[time-nuts] Looking for info about first true radio controlled clock
I'm trying to determine the first product that could automatically decode and display a digital time code. Digital time codes were added to WWV in 1960 and WWVB in 1965. This was before they were added to any satellite signals, or before they were added to LF stations in Europe, such as DCF77. Telegraphic time codes, of course, were around much earlier. I currently think the first true radio controlled clock that decoded a digital time code was the Develco 3391, introduced around 1969. It received WWVB signals and was used by the electric power industry. Does anyone know of anything earlier? Also, has anyone seen a Develco 3391 or have a good picture of one? Any help would be appreciated. ___ 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.

Re: [time-nuts] Looking for service manual for WG SNA23 spectrum analyzer
Hi Gerhard !
I have exactly the same error message. I checked the user manual (page 8-1
of my edition), and they mention that it could be the lithium battery on the
CPU board. Inside mine, the model of the battery is Renata 1000-0B, (CR2477N
Lithium, 3 V, 950 mAh, inside an horizontal orange box 30x30x10 mm) and it's
socketed.
It seems not too difficult to find: http://www.renata.fr/modulesDoc.php, but
I am unable to find reseller in Europe, and there is restriction of export
to UE from the USA... 8-{
There is still a possibility with Farnell, but their site is offline for
maintenance right now.
They said that that's a CR2477N battery inside the package. That one is a
lot easier to find, but I will have to check if I can tear apart the box and
replace only the cell... There is a big warning "Do not open" ...
I will let you know

Jean-Louis

Eningen is not far from here, perhaps a 40 min. drive. Currently I only do

Nice. Except for development boards ($100) the chips ($10) seem to be unobtainium at the moment. Although that will change. John Yes, the most interesting ones seems so. I also hope that this will change... I expect to use them shortly :) A lot of them are readily available, particularly the LM3S8962 with Ethernet but no USB. But the nicer ones, LM3S9B92 and LM3S9B96, seems are not so. I've played around a bit with (less than I would like) with the LM3S9B92 and the LM3S8962, and seems quite good, but not yet used them in a real design.

Re: [time-nuts] Rom Expansion for HP5370B
That is true, the SAM7X... are very nice. I currently use them a lot (mainly for its CAN bus). The bad thing is that they have Ethernet but no phy, so an external phy must be used. In that respect, for an application using Ethernet I would use a Luminary, that has both MAC & PHY on-chip and only needs the magnetics (and USB, and CAN, and whatever...), even nice development kits with lot of GPIO accesibles in 0.1" spaced pads, so no need to solder the LQFP :) , like this http://es.mouser.com/ProductDetail/Texas-Instruments/EKC-LM3S9B92/?qs=sGAEpiMZZMvu0Nwh4cA1wQrEqqirqo8z34F54zcDRdU%3d I suppose that the bus can be attacked by GPIO... but if Ethernet is not needed, I would prefer to not bother too much and have it nicely memory-mapped as in a 7SE512 :) that also is 128-pin instead of 100, but equally easy (or difficult) to solder. But what I would really do is to use my embedded Blackfin processor board, with uClinux, a touch panel and graphical display, and... well, that if I would have the time available, and a second 5370 available :) Regards, Javier El 21/02/2011 18:21, John Seamons escribió: Perhaps an AT91SAM7SE512 - it has an external addr/data bus, with quite flexible configuration, and USB - but no Ethernet :) Regards, Javier One thing I like about the SAM7X512 (and others) is that in exchange for giving up the external bus interface you get USB -and- Ethernet.

But not all. It's possible that the m6800 emulator is not bug-free. I just used one that I found on the net. I have not checked it. Yes, then there are the timing issues. When I first ran the code, and printed every instruction executed, it was clear after a while that a timing loop was running. Now whether this delay is critical to a measurement function or not is unknown to me. Although Poul-Henning can probably tell us with his reverse engineering of the code. Since that poor m6800 is only running at 1.5 MHz you would think that the emulator running on a modern machine would have no problem running many times faster than that. Unfortunately the software stack and USB delays when using that USB-to-parallel adapter in my setup causes everything to run many times -slower- than 1.5 MHz when any I/O is going on. The TI and frequency measurement functions work fine. The slowest effect I noticed is changing the trigger levels. The display update lags by 20 sec or so. Now using a microcontroller with direct bus access is another story. You can clock it from the 5370 10 MHz and use an internal timer to generate the 1.5 MHz bus clock. Then the emulator, now running much faster than the m6800, can count emulated cycles and schedule I/O at the exact time it would have occurred at 1.5 MHz. I will try some more complete testing. ___ 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.
