World's First 'Modern' Computer Turns 60

It was 60 years ago that the first modern computer -- at least according to some -- was born in a lab in Manchester, England. The Small Scale Experimental Machine, or Baby, as it was affectionately known, was the first truly reprogrammable computer that had an analog for RAM. Unlike its predecessors, the ENIAC and Colossus, Baby could accomplish a variety of tasks by inputting different instructions "right out of the box," so to speak (ENIAC and Colossus could theoretically serve multiple uses, but only after several days or weeks of complex rewiring). Baby was the first general purpose computer as we've come to understand the term.
It first successfully completed a set on instructions on June 21, 1948, calculating the highest factor of a prime number, which would be 1.
By todays standards, Baby was absurdly primitive, its CRT memory unit could store a total of 1024 bits of information, with less power than a modern pocket calculator (it could take around an hour to do simple tasks). By contrast even bargain basement PCs today come with 1 gigabyte of memory, or 8 billion bits.
Baby was the immediate precursor of the Manchester Mark I and the Ferranti Mark I, the first commercially available computer. A working replica of Baby is on display at the Museum of Science and Industry in Manchester. [Source: BBC]
