Thanks to everyone who graciously assisted in solving
our problem with the blinking Apple.  (For those few people
left in the world who like me did not know this -- the blinking
Apple means your alarm clock went off.)  We had this problem
spontaneously occur on three of our Macs after running
some experimental code.  Interestingly enough this problem
showed up despite the fact that we did not ever use the
Alarm Clock on these systems.

A couple of individuals pointed out that the information
regarding the blinking Apple is in the Owner's guide.  In 
defense of my dumb question, and for the sake of greater tolerance
everywhere, let me add the following:  I did indeed read the
documentation accompanying the Mac when I first bought it
over a year ago.  However, I have never used the Alarm Clock DA
and so I was not familiar with its behavior.  Unlike many people
I do not memorize manuals -- I refer to them.

Perhaps more important, I would point out that there is no index
entry in the manual for "blinking Apple" and it is not listed
under troubleshooting (since it is not a "problem"). Therefore
without knowing the link between the Alarm Clock and the symptom
I could not diagnose the problem.  I truly appreciate the
help provided to us.  Thank you.
