The design and development of the computer was financed by the US Army. ENIAC was designed by John Mauchly and John Presper Eckert of the University of Pennsylvania. ENIAC consists of 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, and 10,000 capacitors. It weighed 2.7 tons and its volume was about 2.4m x 0.9m x 30 m. It consumed 150 kW of power and occupied about 167m² (1800sf) of space. It used IBM card reader and card punch for input and output devices, respectively.
