Siemens T-100 → ← T-37
|
The T-68D was a rather small teleprinter (telex machine) developed by
Siemens & Halske around 1951. It was the first German post-war telex
machine to hit the market and it soon became an extremely popular model
for commercial telegraphy (PTT) as well as by the European Armies.

The unit measures only 32 x 400 x 39 cm and weights approx. 20 kg.
Unlike many of its predecessors, which printed directly to a paper roll,
the T-68D printed all text as a single line onto a gummed paper strip, making it
ideal for the transmission and reception of telegrams.
The T-68D was also a popular terminal for cryptographic equipment (cipher
machines) of the same era. It was used with a variety of
cipher machines,
such as the Philips Ecolex IV
that was used for the early 1960s onwards by the Dutch Army and by
several NATO counties.

The T-68D was available in several models: with a telephone dial,
for connection to the teleprinter network (telex), suitable for connection
to a radio, with 2-wire of 4-wire interface and with a single or a double
strip printer. The civil version was generally beige, whilst a black one
was available for military use. The latter was usually stored in a green
box.
The T-68D was succeeded by the T-100
which arguably became the most successful Siemens teleprinter ever.
