    Restoration (Mechanical & Electrical) of the Teletype Model 19 (introduced in 1940).

    Nine videos are in the Compilation

    The Teletype Corporation, a part of American Telephone and Telegraph Company's Western Electric manufacturing arm since 1930, came into being in 1928 when the Morkrum-Kleinschmidt Company changed its name to the name of its trademark equipment. Teletype Corporation, of Skokie, Illinois, was responsible for the research, development and manufacture of data and record communications equipment, but it is primarily remembered for the manufacture of electromechanical teleprinters.
    RTTY Electronics (El Sobrante, CA) owned and operated by Paul Cembura, who for many years sold and serviced Teletype machines, is a walking tower of Teletype knowledge.
    Many restoration projects have used parts from Paul.
    Sadly, the last pieces of the Teletype Corporation ceased in 1990, ending the dedicated teleprinter business. One of the three Teletype manufacturing buildings in Skokie remains in use as a parking garage for a shopping center. Every other floor of the building has been removed.
    The other two Teletype buildings were demolished.

    It's interesting to learn that the Teletype Skokie plant has been demolished. I worked there in 1962-64, my first job out of college. My department was involved in research involving magnetic recording. My biggest accomplishment was development of magnetic tape electronics to read magnetic tape at zero speed, or as low as 1/2 inch per second. This was later used by airports to log control tower voice traffic. I sometimes wandered through the manufacturing plant where they were building printers. I was impressed by the hundreds of little pieces that made the printers work. They even had CNC machines turning out tiny screws.

    No restoration of a Teletype model 15 and 19 is complete, without a trip to the Teletype Parts Store ... RTTY Electronics by Paul Cembura (Mr. RTTY) in El Sobrante, CA.

    Oh yes. Another of my projects at Teletype was the design of a transistorized SMD, to replace the clunky relay. These were incorporated on the Model 32, and perhaps others.

    I would like to find a transistor SMD card, just to hang on the wall, remembering my time at Teletype.

    Floyd -

    Did you see the Teletype Model 35 in the video, under one of the wood shelves?
    As we approach the 50th Anniversary for Apollo 8 lunar mission and Apollo 11 landing in 2019 ... there has been an increase in the Retro-Computing and Computer Museums in 1970s computing.
    Teletype Models 28, 32, 33, and 35 are of interest ... especially since Paul Allen and Bill Gates “punched tape” for the Loader and BASIC with Ed Robert’s new MITS Altair 8080 computer. Folder/MITS/History/History.htm

    I still have fond memories of my first trip to Chicago in 1960. I was only eight years old, and shared the back seat of a VW beetle with a couple of suitcases.

    My dad W7YZQ was one of the early RTTY operators, and I was quite familiar with the model 26, and Model 19, clanking away without the covers and soundproofing.

    I can remember when we drove past the Teletype buildings in Skokie, back in the corporations glory days. I thought that was really, really neat . . . .

    I'll bet there is a market for an app the simulates the noise of a teletype for RTTY or even CW decoding. LOL

    Maybe even for all of the digital modes! Could be a nostalgia win. I would buy it … $5 or so.

    Sorry to fall off the thread topic.

    I used to have a Model 15 which is the same as the Model 19 except that it doesn't have the "re-perforation" unit. My wife banned it to the utility room which was at the end of the carport in the first house we owned (that was my senior year in college - the house payments, etc., were less than what we were paying for rent).

    It did make a "little" bit of noise when running!

    How about a font for model 33?

    (£ instead of $, oh well)
