You know, I had wondered in times past if it were indeed possible to
make all the various logic gates with discrete components. This clock
proves that it can be done - the manual is available for free download
that describes in detail all the circuits.
Forgive me - I'm a little foggy this morning after shoveling so much
snow yesterday after arriving home from work. Is there a type #492
battery, or should I power the clock with 492 individual batteries?
