The IBM Selectric Touch Keyboard with buckling-spring switches was named after the typewriters. The IBM beam spring was succeeded by the now more famous buckling spring mechanism. The IBM Wheelwriter 1500 has many advanced features that automate and simplify all of the typing applications in todays busy office. The IBM Beam spring switch in IBM beam spring keyboards had been designed specifically to have both key feel and sound reminiscent of that of the Selectric typewriters. Product Description A typewriter in the hardworking tradition of the classic IBM Selectric (R) typewriter. Selectric typewriters have been cited as precursors to all clicky computer keyboards. Many Selectric typewriters have also been converted into teletypes for use as a computer terminal. According to the IBM Products Division press fact sheet published in August 1976, The typewriter prints by means of a single, interchangeable sphere-shaped. They were available in models with different platen width, which generally came in 11", 13", and 15" options. The first Selectric series was succeeded by Selectric II and Selectric III series. The problem is, IBM stopped making the single printing element that makes those typewriters so special. There were several models and lines of Selectric typewriters and several specialist models with editing ability and access to memory. It is most renowned for its implementation of a spherical type-element that rotates according to digital information inferred by a whiffletree. His videos should be held up as models of how to present complex technical information visually.The Selectric is a series of electric typewriters that IBM introduced in 1961. You may remember Bill, aka Engineer Guy, from the office copier anatomy video we hit last July. Doubly awesome is the fact that the video features an appendix (yes, a video appendix) which focuses exclusively on the whiffletree itself, closely illustrating its operation with a simple 2-bit case. It transformed the speed, accuracy and flexibility with which people. Brilliant science-and-technology documentarian Bill Hammack, professor of Chemical and Biochemical Engineering at the University of Illinois, has produced this fascinating video anatomy of IBM’s classic Selectric typewriter, in which a 7-bit whiffletree is employed to convert keypresses (digital) to precisely coordinated tugs (analog) on the control cables that rotate and tilt the type ball. The IBM Selectric typewriter was the first of its kind, originally created back in 1961. Heck, that’s the word of the month, as far as I’m concerned.Ī “whiffletree” is a mechanical digital-to-analog converter.
