The Harvard Mark IV was an electronic stored-program computer built by Harvard University under the supervision of Howard Aiken for the United States Air Force. The computer was completed in 1952.[1] It stayed at Harvard, where the Air Force used it extensively.
The Mark IV was all electronic. The Mark IV used a magnetic drum and had 200 registers of ferrite magnetic-core memory (one of the first computers to do so). It separated the storage of data and instructions in what is now sometimes referred to as the Harvard architecture; however, in the context of microcontrollers, the term was not coined until the 1970s.[2]
