This story is tacked up on the wall inside the clock room at the Arecibo Radio Observatory. The "Keeper of the Clocks" here eagerly awaits a true atomic watch based off the CSAC SA.45s chip that @daniel-cussen mentioned.
How go the repairs there? I loved visiting the observatory and museum hall on my first few trips to PR.
Did they manage to keep all or most of it open to the public or is it now purely a science installation?
Edit: Ah, I found a link to the visitor's center ( http://www.naic.edu/outreach/describe_fset.htm ). Happy to see it is still serving the public and looking forward to taking my kids there next trip down.
