It was developed by J. Presper Eckert and John Mauchly at the University of Pennsylvania. The project began in 1943 and was completed in 1946. The machine was huge; it weighed 30 tons and contained over 18,000 vacuum tubes 也许早期最具影响力的类似计算机的装置应该是电子数字积分计算机 或简称 ENIAC。它是由宾夕凡尼亚大学的. Presper Eckert和John Mauchly研制的。该工程于1943年开始,并于1946年完成。这台机 器极其庞大,重达30吨,而且包含18000多个真空管。 《什第机专出美语Chapter 1 The History and Future of Computers 计算机专业英语 1-7 1.1.1 The ENIAC Perhaps the most influential of the early computerlike devices was the Electronic Numerical Integrator and Computer, or ENIAC.
