Data emisji: Lis 07, 2010

Using slow motion video Bill Hammack, the engineer guy, shows how IBM's revolutionary "golf ball" typewriter works. He describes the marvelous completely mechanical digital-to-analogue converter that translates the discrete impulse of the keys to the rotation of the type element. (This is the typewriter featured on the television series Mad Men.)
