A while back I purchased a Symmetricom ND4 clock on eBay -- it was lasted as "Not Working / for parts only", and it turns out that was true -- the processor board had issues. I wasted much time trying to fix it, and then simply removed it -- I'm now using a Raspberry Pi Zero to drive the display part (over the SPI bus). It runs NTPD, and so is more than accurate for a wall clock.
Total cost was less than $100 (if you ignore the money wasted on trying to revive the old board :-) ) Some details here: https://github.com/wkumari/symmetricom-nd4-python/blob/master/symmetricom_raspberrypi_clock.py An example ND-4 on eBay https://www.ebay.com/itm/New-Symmetricom-ND-4-820-1444-Digital-Clock-Time-Display-90-264v-ac/302748531081?hash=item467d37f989:g:GEUAAOSwpHpbBqm4 -- this one is new, if you wait a while you should be able to find a dead one...

This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://lists.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
