Hi All,

I wonder if the clock could be made with tubes.  Imagine what it might look like.

Best Wishes

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?
