    Teletype Corporation commemorated its Golden Anniversary in 1957. Fifty years is a short span in thehistory of Communication. Yet in that time, Teletype has developed its equipment from primitive models with limited use or acceptance, to the speedy precision machines which are an indispensable part of modern communications. Today Teletype equipment is an important economic tool, serving in many and varied ways the demands of our way of life. This is the story of Teletype. It is a story of challenges met and problems solved, of faith in the future and of the surpassing of what were only dreams.

  • A Brief History of Data Communications Data
    A Brief History of Data Communications Presently, the United States is the most technologically advanced country in the area of telecommunications with about; 126 million phone lines, 7.5 million cellular phone users, 5 thousand AM radio broadcast stations, 5 thousand FM radio stations, 1 thousand television broadcast stations, 9 thousand cable television systems, 530 million radios, 193 million television sets, 24 ocean cables, and scores of satellite facilities! This is truly an "Information Age" and sometimes, you need to look at where we've been in order to see the future more clearly! Data Communications Milestones What hath God Wrought? These famous words were telegraphed by Samuel F. B. Morse in 1844, although the patent for the "electric telegraph" was submitted in 1937 by Charles Wheatstone. By the time of the Civil War, telegraph communications spanned the United States, and in 1866, the first trans-Atlantic cable was laid between the US and France (Werner von Siemens from Germany was one of the pioneers in the development of reliable submarine cables). The basic elements of Morse code were the dot ("dit") and the dash ("dah"). In International Morse code (the most prevalent of the Morse code variants), the dot was the minimal duration element, with the dash equal to three times the duration of the dot. Electrically, current flows with both dots and dashes. The time between each element of the same character was one dot. The amount of time between each character was three dots; and the time between words was equal to seven dots! During these "idle" time intervals, the telegraph line was open (no current flow).

  • History of Telegraphy from the Teletype Museum
    History of Telegraphy from the Teletype Museum Ransom D. Slayton, Consultant 1983 (Document Notes) The Teletype Museum display was set up several years ago by Charley Hill and Ken Lovitt, and served for some time as a magnet attraction for visitors to the Teletype plant. Later, due to the compelling demand for more office space as the company expanded, the Museum was dismantled and the equipment on display sent to storage. A record set of slide pictures was made just before this occurred, and this program is a "walk through" of the Museum as it appeared in its better days. join us for a trip back into the History of the Telegraph Art as illustrated by the machines developed by the in- ventors who contributed so much to communications progress in the old days. 1. Our greeting is an appropriate "START HERE" with the beginning of a series of numbered captions covering various steps in THE HISTORY OF TELE- GRAPHY. Early forms, before 1820 include semaphores and electro-chemical signaling methods, but historical records tell of signal fires, smoke sig- nals, and even an "encoded torch" system in which the lighted torches were placed in numbered notches on top of high walls, the combinations of tor- ches thus indicating the letters, numbers or pre-selected words being transmitted. It was great for both day and night, but look out for rain or fog!! 2. Most people think of telegraphy in terms of the old Morse code Key and Sounder, so this was the first display. The Sounder had a reflector box behind it, amplifying the clicks of the "Dots and Dashes" to the operator's ears.

  • Chad Is Our Most Important Product
    CHAD IS OUR MOST IMPORTANT PRODUCT An Engineer’s Memoir of Teletype Corporation Jim Haynes The author operating W5YM in 1957 1 I. How it all started When I was growing up in a small town I thought it was an awfully boring place. Now I realize that I had some opportunities that probably would not have been available in a larger city. For one thing, it was possible for a kid to hang out at the newspaper office, telephone office, telegraph office, or radio station and watch a Teletype machine in operation. Things were slow enough that the people who worked there usually had time to answer questions. When I wanted to understand how a Teletype machine worked the wire chief at the telephone office let me borrow the “green book”1. After reading all about selector cams and swords and code bars and pull bars I could drop in to the Western Union office where the manager, a friend of the family, let me play with a little-used printer and see in action all the parts I had read about. Another advantage to living out in the sticks was that television arrived very late. This allowed a pretty good news stand to remain in full operation through most of my teen years. Jack’s News Stand carried several magazines of interest: Radio-Electronics, Radio & Television News, and the amateur radio magazines QST and CQ. Hugo Gernsback’s Radio-Electronics ran a series of articles by Ed- mund C. Berkeley about digital computers, which gave me an early introduction to binary arithmetic, Boolean algebra, and logic circuits.
