Engineering:Model K (calculator)
From HandWiki
The Model K was an early 2-bit 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.[1][2][3][4]
