Harvard Mark III

The Harvard Mark III was an early computer developed in the 1950s at Harvard University as part of a series of computers known as the Harvard Mark series. Specifically, the Mark III was designed to be a more advanced version of its predecessors, the Harvard Mark I and II, which were early electromechanical computers. The Harvard Mark III was notable for its use of vacuum tubes for electronic computation, making it faster and more reliable than the earlier mechanical and electromechanical designs.
