The 1969 IBM Magnetic Card Selectric Typewriter (“Mag Card”). A look back at a vintage 1969 office environment with dictation machines and the Mag Card system. The Mag Card and its successor machines facilitated the link between electronic typing and computer storage of data, and increased office productivity. This was followed by the IBM Mag Card II, which we cover in another video available here: youtube.com/watch?v=D0dsYwBV2F8

$Computer History: Exploring UNIVAC 1 Components (with UNIVAC II vacuum tube module compared) 1951-58 UNIVAC 1 Computer: Today we take a look at some of the UNIVAC 1 components, and compare some of the UNIVAC II boards with UNIVAC I boards. High Resolution images highlight this informal compilation of UNIVAC 1 modules and components. Shown are various modules, board components, mercury memory tanks and other aspects of the machine, and a comparison of 1951 UNIVAC 1 circuit boards with those of the 1958 UNIVAC II (as seen in Jerry Seinfelds movie Unfrosted 2024) and later models. A unique, close up look of some of the early UNIVAC components. If you like board-level components and early tech, you may find these images interesting. UNIVAC II (aka UNIVAC 2) was outdated by the early 1960s. The UNIVAC III of 1960 was short lived, and IBM gained control of the large computer market by the time it was introduced. Uploaded for educational and historical purposes only. UNIVAC is a trade name of UNISYS Inc. today. - UNIVAC was designed by J. Presper Eckert and Dr. John Mauchly, creators of the ENIAC (1946) and the BINAC (1949) . Run time: 9 minutes.
