Ruminations on the electronics industry from David Manners, Senior Components Editor on Electronics Weekly.

The World’s First Electronic Calculator

The world’s first electronic calculator was marketed in 1961 by the UK company Bell Punch named after its first product – a ticket punch with a bell for conductors on trams and buses.

The Bell Punch Company sold its electronic calculator through its Sumlock Comptometer division with the brand name Anita.

Now this was variously interpreted as an acronym for A New Inspiration To Arithmetic or A New Inspiration To Accounting or in honour of the christian name of their designer’s wife.

Vacuum tubes, cold-cathode switching tubes and Dekatrons were used for logic, and and nixie tubes were used for the numerical displays.

They were manufactured in Uxbridge and Portsmouth
