[time-nuts] HP59309A HP-IB Digital Clock Operating and Service Manual

[Martin Fischer]

   Hello Community,
   thank you all for your hints concerning the HP59309A Clock
   and your kind assistance with making available the Operating and
   Service Manual.
   My HP 59309A had a real problem: One of the input protection diodes
   of the EXT FREQ STD input was shot. Suspect the previous owner
   confused the EXT FREQ STD input with the line input...      ;-)
   Regards
   Martin
