Harvard Mark III
It was built at Harvard University under the supervision of Howard Aiken for use at Naval Surface Warfare Center Dahlgren Division.Aiken boasted that the Mark III was the fastest electronic computer in the world.This separation of data and instructions is now sometimes referred to as the Harvard architecture although that term was not coined until the 1970s (in the context of microcontrollers).This was a bottleneck in the computer and made the access time to data on these drums long – 80,000 microseconds.Naval Proving Ground at the U.S. Navy base at Dahlgren, Virginia in March 1950.
