ENIAC had neon lamps and oscilloscopes to show current machine state, but these were usually only used for test & debug purposes. The only real output device on ENIAC was one electromechanical IBM cardpunch that could punch 100 cards per minute, 8 ten digit numbers per card maximum.
The ENIAC was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory, but it's first use was in calculations for the hydrogen bomb.

ENIAC was the first computer.
it originally cost $500,000, and was government funded. Check below for more information http://en.wikipedia.org/wiki/Eniac

what was eniac?
Perhaps your thinking of ENIAC, but no ENIAC was designed for calculating artillery firing tables.Both the Norden and Sperry analog computer bombsights preceded ENIAC, but they are electromechanical not electronic. I don't know when the first electronic computer bombsight was made, but remember the Nordens were still in use in the Vietnam war! You can't use tables for bombing, the calculations must be done in real-time.
ENIAC was unplugged as it runs on technology that makes the average 10-year-old Linux box seem like a Concorde compared to a turtle. It did calculations at a rate of under 5000 additions a second. Nowadays new computers (running the Intel Core i7 Extreme Edition i980EE processor) can do well over 100,000 MILLION calculations per second, even that 10-year old Linux box can do about 3,561 MILLION calculations per second (running AMD Athlon processor). BTW: for comparison; the average person working with pen and paper can do about 0.0119 calculations per second Sourced from http://en.wikipedia.org/wiki/Instructions_per_second
Twenty 10 digit accumulators for working data. Punchcards for I/O data.

The ENIAC computer was finished in November, 1945.
