Leading Edge computer called the CSIRAC, which is claimed to be the first computer in the world to play music, is on its last legs in an Australian museum -- like Mageek it's pegging out. The machine was built in 1949, weighs a few tons, and consumed enough electricity to light up a street.
The machine was the fourth computer to be built anywhere in the world, ran at 0.001MHz, and had a massive 2000 bytes of memory and a behemothic 2500 bytes of storage.
And it's still running, now safe in the Melbourne Museum, in Australia.
