Bill! And it will be programmed in Assembly!Are you using some tricks to
improve the reliability of "reading" AC line? Either HW or SW. In Europe AC
time is currently running 32 seconds late since the
A genuine DS3231 does a remarkable job of keeping accurate time. I have one
in a wristwatch prototype board that has not been updated for more than 4
years, and it's still within 1 minute of the real time.

Outstanding Bill! And it will be programmed in Assembly!
Are you using some tricks to improve the reliability of "reading" AC line?
Either HW or SW. In Europe AC time is currently running 32 seconds late
since the beginning of the year. It will catch up, as it did in 2018 when
the grid had "lost"
I promised to post some details on my current Nixie nightmare. I present:
The BRS Clock
The current version of the clock is in 2 (or more) PCBs. This was done to
allow changes to the display type by only either changing the display board
or the display cluster boards. The board can be
