Like the Colossus, ENIAC required rewiring to reprogram until April 1948.See #Improvements In June 1948, the Manchester Baby ran its first program and earned the distinction of first electronic stored-program computer. Though the idea of a stored-program computer with combined memory for program and data was conceived during the development of ENIAC, it was not initially implemented in ENIAC because World War II priorities required the machine to be completed quickly, and ENIAC's 20 storage locations would be too small to hold data and programs.
