Deltar

The Deltar (Delta Getij Analogon Rekenmachine, English: Delta Tide Analogue Calculator) was an analogue computer used in the design and execution of the Delta Works from 1960 to 1984. Originating with Johan van Veen, who also built the initial prototypes between 1944 and 1946, its development was continued by J.C. Schönfeld and C.M. Verhagen after van…
