Hi all,

I don't have any exciting stories, but my father bought an HP-12C
after his HP-80 started developing keyboard problems.  I still have
both calculators but haven't used them to any extent.  The 12C claims
to be made in Malaysia, and its serial number is MY72800314.  I guess
this indicates when it was made (28th week of 1987 ??), and also that
it contains a hidden function giving the value of pi... :-)
