Calculators: Sharp
Famous Japanese manufacturer that worked with Rockwell to create some of the earliest electronic calculators.  Most models had Elsi, Elsimate or Compet in their name somewhere so these have been left out on the listing below.  Sharp manufactured their calculators in Japan and Korea.  The model numbers are very confusing, with an incrementing 8,000 system and a parallel three digit almost always incrementing system) so the below examples are listed in date/design order.
