Harvard Mark IV

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.[1] It stayed at Harvard, where the Air Force used it extensively.The Mark IV used 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 although that term was not coined until the 1970s (in the context of microcontrollers).[2] This computer hardware article is a stub.
