Thanks to all those who replie don this subject. I'm using an old VP Oncore purely for timing.
The situation where the RTC stops at low voltage but the memory lingers on resulting in the wrong time for the Almanac is a fascinating one of which I was not aware. I may do some experiments to see at what voltage the RTC stops. In the meantime the discussion prompted a baord redesign to find some real estate for a Li cell :-) Thanks again, Morris _______________________________________________ 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.
