IAS machine

[1] The general organization is called von Neumann architecture, even though it was both conceived and implemented by others.[2] The computer is in the collection of the Smithsonian National Museum of American History but is not currently on display.[4] Hewitt Crane, Herman Goldstine, Gerald Estrin, Arthur Burks, George W. Brown and Willis Ware also worked on the project.Although some claim the IAS machine was the first design to mix programs and data in a single memory, that had been implemented four years earlier by the 1948 Manchester Baby.The requirement that instructions, data and input/output be accessed via the same bus later came to be known as the Von Neumann bottleneck.
