Ferranti Star

For people who check facts
The Ferranti Star was the first 'computer', in the modern sense of the term, to go on sale commercially in the UK. It was effectively the same as Prof. F C Williams' 'baby' design but very much miniaturised. Although it went on sale in 1949, it was not until 1951 that the first one was delivered to Manchester University.
