T-100
Electromechanical teletypewriter · 1958 - this page is a stub

T-100 is an electromechanical desktop teletypewriter (teleprinter, telex), 1 introduced in 1958 by Siemens in München (Germany) as the successor to the aging T-37. It was available in a variety of enclosures and is by far the most successful teletypewriter ever made by Siemens. It was used on the worldwide TELEX network, but also as a terminal for a number of cipher machines and for the first generation of computers. It was succeeded in 1976 by the largely electronic T-1000 [1].
