Siemens T100 Teleprinter: page printer from early 60s
Filed under: Gadgets
In this day an age if you heard about a product called the Siemens T100 you would think it’s a new mobile phone from Siemens as I have not heard about that model of cell phone yet.
The fact is that the Siemens T100 is a page printer that dates way back to the 1960’s and was used widely by all of the UK military services and on the commercial telex system.
Telegraphy basically is a “long-distance transmission of written messages without physical transport of letters” and you can read more on Telegraphy in depth at wikipedia.
Known as telegrams or cablegrams, were telegraphy messages that got sent by the telegraph operators using Morse code.
If you have any other information on the Siemens T100, please share a comment below.

I was a teleprinter mechanic and worked on these machines in the late 60s and early 70s. Well designed on the whole and easy to repair. Could run at either 50 bauds (telex and private wire) and 75 bauds for private wire circuits. The photo is a telex connection with dial for sending receiver address and he unit has a tape transmitter (RHS) and tape reperforator (LHS).The box the dial is attached to would be the connection relay set. The model is a Siemens M100 series 1. The later model, Series 2, had a larger sound proof cover and minor tech changes.
