The left end consisted of electromechanical computing components. The right end included data and program readers, and automatic typewriters. The Harvard Mark I, or IBM Automatic Sequence Controlled Calculator (ASCC), was one of the earliest general-purpose electromechanical computers used in the war effort during the last part of World War II.
The Manchester Mark 1 was dismantled and scrapped in August 1950, [28] replaced a few months later by the first Ferranti Mark 1, the world's first commercially available general-purpose computer. [1] Between 1946 and 1949, the average size of the design team working on the Mark 1 and its predecessor, the Baby, had been about four people.
The limitation of the Mark 1 computer did not allow for a whole game of chess to be programmed. Prinz could only program mate-in-two chess problems . The program examined every possible move for White and Black (thousands of possible moves) until a solution was found, which took 15–20 minutes for easy problems but several hours in general. [ 17 ]
The machine was fairly representative of first-generation valve-driven computer designs.It used mercury acoustic delay lines as its primary data storage, with a typical capacity of 768 20-bit words, supplemented by a parallel disk-type device with a total 4096-word capacity and an access time of 10 milliseconds.
Harvard Mark I / IBM ASCC, left side. Howard Hathaway Aiken (March 8, 1900 – March 14, 1973) was an American physicist and a pioneer in computing. He was the original conceptual designer behind IBM's Harvard Mark I, the United States' first programmable computer. [1] [2]

Mark I Perceptron machine, the first implementation of the perceptron algorithm. It was connected to a camera with 20×20 cadmium sulfide photocells to make a 400-pixel image. The main visible feature is the sensory-to-association plugboard, which sets different combinations of input features.
