THE CALCULATOR REFERENCE
Last Update: Feb 04, 2007
Welcome to The Calculator Reference
Here you will find a wealth of data I have collected over the years on HPs,
on TIs and on my all time favorite mechanical calculator, the CURTA.
My favorite calculators are HPs but I don't plan on this page even starting
to compete with "The Museum"! Look around,
enjoy yourself, and marvel over how these little silicon devices changed the world.
