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. One of the first programs to run on the Mark I was initiated on 29 March 1944 [1] by John von Neumann.
1 Sweden's first computer and was the fastest computer in the world for a brief time IBM NORC: 1954 1 Built by IBM for the US Navy Bureau of Ordnance, it was the first supercomputer and the most powerful computer in the world for at least 2 years. 9,800 tubes in logic.
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 Manchester Mark 1, which used Williams tubes, was successfully commercialised as the Ferranti Mark 1. Some early computers in the United States also used Williams tubes, including the IAS machine (originally designed for Selectron tube memory), the UNIVAC 1103, IBM 701, IBM 702 and the Standards Western Automatic Computer (SWAC).
