Sure, I remember the HP-01!  It was HP's entry into the digital watch
market.  Had a little calculator (not RPN), with the key poker hidden
in the band clasp.  One of my friends in high school had one (that gives
you some indication as to my age!).  I'll bet if they put one out now,
RPN wouldn't be a problem.
 
 
I know the thoughts expressed here are my own because no one else would claim
them!
