The earliest computer ever designed was Charles Babbage's Analytical Engine, which he conceived of way back in 1837. Unfortunately, he never completed it, and to this day a fully-functioning model has never been built. But that's about to change.
Now, blogger John Graham-Cumming is trying to raise about $640,000 to build the steam-powered contraption using the original blueprints. As he says, "What you realise when you read Babbage's papers is that this was the first real computer. It had expandable memory, a CPU, microcode, a printer, a plotter and was programmable with punch cards. It was the size of a small lorry and powered by steam but it was recognizable as a computer." And it would be pretty amazing to see it in action almost 200 years after it was initially designed. Want to donate to the cause? Click here.
