On February 15, 1946, the world's first general-purpose electronic digital computer "eni gram" (ENIAC) was successfully developed. "Eni, was" a success in the history of the computer is a monument, is human development in computing's history, the arrival of a new starting point.

"Eni, was" the first computer design scheme, is by the 36-year-old American engineers moche forward to computer analysis is the main task of the shell orbit. The United States JunXieBu funding support research work, and to establish a special research group, the moche and responsible. The chief engineer by only 24 years old, as the echoviruses, crew members, axel is a mathematician, and another logic Bob cox family. "Eni gram" were used 18000 vacuum tubes, plus 1500 a relay and other devices, and its overall proct made about 90 square rice, weighed 30 tons, covers an area of 170 square meters, the need to use a more than 30 meters long big room to store, is a real colossus. This computer power consumption for 140 kilowatts of computer, speed 5000 times per second for addition, or 400 times multiplication, than the relay mechanical computer 1000 times faster. When "eni, was" on public display, a shell with 20 seconds of the orbit can work out, the shell of the body than a flight at a faster rate. Eni gram of memory is electronic device, and not on the rotation of the "beat". It can in a days to complete tens times multiplication, about a personal use desktop computer operation at 40 years of work. It is according to the decimal, not by binary to operate. But which also use a small amount of work as a binary way tube, therefore in the work had to machine the decimal into binary, and in data input, output change again back to the decimal. "Eni gram" was first on trajectory calculation and design for special computer. But then through the change in control board the connection mode of insert to solve different problems, and become a general-purpose machine. It's a retrofit machine used for the development of the hydrogen bomb. "Eni gram" program using external plug-in, whenever a new calculation, to have to connect circuits. Sometimes a few minutes or calculation, and want to spend a few hours or 1 ~ 2 days of time lines for connection, this is a weakness. It's another weakness is storage capacity is too small, or, at best, only save 20 a decimal number 10. British radio engineer association general mountbatten "eni gram" appear as "was born an electronic brain", the "computer" from the name of the rounds.

On February 15, 1996, in "eni, was" come out 50 years anniversary, vice President al gore in the university of Pennsylvania was held a memorial ceremony, once again, the machine has the press sleep 40 years of large computer start button. Al gore in the year to attend "eni, was" the development, is now living scientists speech: "I would like to develop in this computer pioneers of congratulations." Eni, was on two rows of lights to the rhythm of the accurate blink to 46, marks it came out in 1946, and then blink to 96, marks the computer age since the beginning of 50 years.
