SB-634 Question!!

[Guy G. Giacopuzzi]

I know the electronic clocks of the same era (made by Heathkit...)"timed 
themselves" on power line frequency; if this is slightly off, it made 
those clocks off--at the time it seemed they were pretty accurate....now 
the question, does the 634' use the same power line sync that the other 
clocks used?  I don't know the answer to that...it would be curious to 
see if they use the same clock chip...I'm almost positive they use the 
same high voltage display.  Heath was famous for using similar 
chips/circuit designs in different kits...
