Model K (calculator)

Last updated

The Model K was an early 1-bit Eletromechanical binary adder built in 1937 by Bell Labs scientist George Stibitz as a proof of concept, using scrap relays and metal strips from a tin can. The "K" in "Model K" came from "kitchen table", upon which he assembled it, It would later become the basis for the technology of the Model I Calculator. [1] [2] [3] [4]
