HP Calculators. Many
pocket calculators have interesting stories, but the calculators
built by Hewlett Packard have a special place in the calculator history. In
the following pages, we present their 30+ year long history in
chronological order.
HP calculators were manufactured in groups of similar types,
called families or series. The calculators in each family had
similar characteristics, size and color (and price).
