Problem with Early Computers [PDF ebook] 

Computer technology has come a long way from the machines that took hours to do even simple tasks. The history of computing is full of computers that were the size of a room and did very little. Years of technological developments have helped turn those giant machines into tiny machines that put the world at our fingertips, but it certainly wasn’t easy. From power failures to broken parts and wacky inventions doomed to fail, readers discover that the history of computers is filled with outrageous bloopers and pitfalls that eventually led to the technology we take for granted today.
