Hi Paul,
Glad I didn't say no aircraft clocks use a 60Hz timebase! I wonder if they used
a commercial (non-aircraft) movement? The design seems to break the normal
aircraft design premise that a single failure should not cause the loss of more
than one duplicated system. Unless the clocks have

Excellent Paul! Many thanks for taking the time to prepare this data for
me. I've no idea which variation mine is, but I guess I can assume (for
now) that it doesn't require an external timebase because there's only one
connector on the back.
I'll hook up power and see what happens. As soon as
Well, I found some stuff on this clock... from a few handwritten notes I
made several years ago, there exist both types; those that have an
internal timebase, and those that require an external timebase. The
clock that I can put my hands on right now is an A15586; I have a couple
more. The
