National Semiconductor, U.S.A.
Alongside a vast range of semiconductor products, National Semiconductor manufactured calculator integrated circuits and in the mid- to late 1970s introduced a very successful range of hand-held calculators under the National Semiconductor and Novus names. Calculators ranged from the very basic Novus 650 "Mathbox" to complicated specialised models.
