30 abr 1929 ano - IBM Model 016 keypunch

Descrição:

This early IBM keypunch, the Model 016, was introduced in 1929. Its automatic feed and ejection features aided key punching and reduced operator fatigue. These mechanisms ejected one card and fed another in 0.65 seconds. The feed mechanism was developed by F. Lee and G. F. Daly; the ejector mechanism was developed by F.W. Richter of IBM's German operation. The Model 016 also had a duplicating feature that meant that any information common to one card could be duplicated on another accurately and rapidly. It was a long-lived product, not being withdrawn from IBM's product line until the 1950s.
