DNA B Structure: Data for EDSAC. In copyright. Source: Wellcome Collection.
Tabular data (DNA B Structure co-ordinates), supplied by Maurice Wilkins, including a brief note to Crick from W E Seeds on an error in co-ordinates (1956, King's College London). All data is dated February, 1957.
The file also includes a number of EDSAC Library Specification Sheets, Programme Sheets, and various operational guidance sheets.
EDSAC (Electronic Delay Storage Automatic Calculator) was the world's first stored-program computer to operate a regular computing service. Designed and built at Cambridge University, EDSAC performed its first calculation on 6th May 1949, and was particularly used by crystallographers, replacing the punched card equipment used for Fourier syntheses.
