how far we've come
As well as the displays relating to Bletchley's wartime codebreaking activities, Bletchley Park also houses various related collections. There's a post-war collection of calculators and computers, many of them, astonishingly, still working. This array of disk drives is part of an ICL 2900 series computer. I worked with its predecessor, the 1900 series, in the 70s. Each drive cabinet is about the size of a washing machine and the removable disks (resting on top of the cabinets) are about 100Mbyte. The total huge array was probably just about the capacity of the 2Gbyte memory stick I had in a bag on my belt and certainly smaller than the 4Gbyte memory card in the compact camera that took this photo!
