Originally named the V1, the Z1 began development in 1936 by Germany's Konrad Zuse in his parents' living room and is considered the first electromechanical binary programmable computer. The Z1 had 64-word memory (each word contained 22 bits) and a clock speed of 1 Hz. Both programming and output were generated using punch tape with a specific reader. Below is a picture taken in 1937 of the Z1 computer.
