Wang also soon brought out its Series 300 calculators, which were oriented toward business rather than scientific calculations. One form of this calculator, the LOCI II, had rough programming capabilities. The Wang LOCI, sold from1965, carried out all these operations at the touch of a key, and had further keys for finding squares, inverse squares, inverse square roots, and inverse logarithms. The same year a rival firm, SCM Marchant, offered calculators with and without the ability to take square roots. In 1966 Monroe International Corporation, a descendent of an American calculating machine company, introduced the Monroe EPIC 3000, an electronic calculator that not only performed basic arithmetic but took square roots. The Anita, Friden, Sony, and Sharp calculators performed the four basic arithmetic operations of addition, subtraction, multiplication, and division. These early electronic calculators were large, heavy, expensive products, with keyboards patterned after calculating machines. Also in 1964, the Massachusetts firm of Wang Laboratories announced its Wang LOCI, a “logarithmic calculating instrument.”

These included the California manufacturer of calculating machines, Friden Japanese consumer electronics companies selling under the trade names Sony and Sharp and the California inventor Thomas E. In 1961 Sumlock began to sell the Anita Mark VII and Anita Mark VIII electronic calculators, compact vacuum tube machines that could do simple arithmetic.īy 1964 several other companies were considering the electronic calculator market, using transistorized circuits rather than tubes. If you lose the calculator or it is stolen, inform customer support immediately.As early as the late 1950s, engineers at the British firm of Sumlock Comptometer Limited, a manufacturer of adding machines, imagined that electronic circuits might be used to carry out arithmetic operations in calculators that fit on a desktop.
