But they did.... quote from the Science Museum "Analytical Engine Mill by Henry Prevost Babbage, 1910. Babbage bequeathed his workshop, experimental work, drawings and other material relating to the Analytical Engine to his son Henry Prevost. To 'justify the confidence he had shown' in him, Henry wished to realise in metal some of his father's designs. This portion of the mill, the arithmetic unit and printing mechanism, was the result. It was worked on intermittently from the 1880s until 1910 in the workshop of R W Munro. It was designed to perform addition, subtraction, multiplication and division. Henry records that in 1910 it printed the first twenty two multiples of Pi to 28 places. These were later found to contain mistakes. It is questionable whether the machine ever worked." www.sciencemuseum.org.uk There is a picture of the Engine on the web site. Suzanne Giles PS we are implementing a new bibliographic system at the British Library in the UK and are using Unicode as we use so many different scripts when cataloguing. This news group is very interesting.
