The History of Computers [ala Techking]
This is great (thanks Techking for creating it and @djilk for pointing it out). A humbling look at where computers started and how they advanced. There are many missing, including some of the more recent super-duper computers produced to work on some nasty computational problems and a couple built to become chess-masters and Jeopardy winners, but the key ones are pretty much all here.
