Rockwell-ANITA Desktop & Hand-held Calculators
Most of the calculators listed here carry the Rockwell logo on the front and were produced after the takeover of Sumlock-Anita Electronics by Rockwell International in 1973. Some were manufactured at the Sumlock-Anita factory in Portsmouth and examples of them can be found with the legend "Made in Great Britain". Almost all of these machines use Rockwell integrated circuits.
A company internal memo of October 1974 lists the Rockwell calculator models that the company will be dealing with after the takeover and says "For the first few months we will import machines from the U.S.A. but active steps are now being taken to ensure that production of this new calculator range will commence at Portsmouth early next year".
