BINAC (Binary Automatic Computer) is an early electronic computer that was designed for Northrop Aircraft Company by the Eckert–Mauchly Computer Corporation (EMCC) in 1949.[1][2] Eckert and Mauchly had started the design of EDVAC at the University of Pennsylvania, but chose to leave and start EMCC, the first computer company. BINAC was their first product, the first stored-program computer in the United States; BINAC is also sometimes claimed to be the world's first commercial digital computer[3] even though it was limited in scope and never fully functional after delivery.
