Friday Fun-Fact: The ENIAC First Computer 1946 (4pics)

Here is a Fun-Fact for your Friday entertainment... 
The ENIAC was the first electronic general-purpose computer designed and built in 1946 with the budget cost of $500,000 (nearly $6-Million in 2010, adjusted for inflation)... 

ENIAC could make five thousand additions in seconds, which seemed very fast, by today's standards that is extremely slow. Most computers today do millions of additions per second in comparison. That is a huge difference as any one can plainly see.
Besides its speed, the most remarkable thing about ENIAC was its size and complexity. ENIAC contained 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints. It weighed more than 30 short tons (27 t), was roughly 8 by 3 by 100 feet (2.4 m × 0.9 m × 30 m), took up 1800 square feet (167 m2), and consumed 150 kW of power (leading to the rumor that whenever the computer was switched on, lights in Philadelphia dimmed). Input was possible from an IBM card reader, and an IBM card punch was used for output. These cards could be used to produce printed output offline using an IBM accounting machine, such as the IBM 405.
