On Humanist there was an announcement from the Hagley Museum and Library that they had put up a 1969 Sperry-UNIVAC short film An Introduction to Digital Computers. The 22 minute short is a dated, but interesting introduction to how a digital computer works. The short was sponsored by Sperry-UNIVAC which had its origins in the Eckert-Mauchly Computer Corporation founded by Eckert and Mauchly of ENIAC fame.
The museum is in Delaware at the site of E.I. du Pont gunpowder works from 1802. The Hagley library is dedicated to American enterprise and has archival material from Sperry-UNIVAC:
Hagley’s library furthers the study of business and technology in America. The collections include individuals’ papers and companies’ records ranging from eighteenth-century merchants to modern telecommunications and illustrate the impact of the business system on society.
