Siemens T100 Terminal with Paper Tape - Available

[nico de jong]

Dominique,
Well, that is in principle very easy.
You need a COM port (or simulator) and a little box converting RS232 to 
50 BPS serial.  Diagrams can be found everywhere. But you could also 
look at www.i-telex.net. This is a (primarily) german "band of 
brothers". They have set up an international of teleprinter users, so 
they can communicate through internet. Nice system, can recommend it.
If you have (or get) a special interest in teleprinters, I have the 
software for a teleprinter exchange, also interfacing to i-telex.net
In this way, you can have a complete telegraph office in your living 
room (more likely : a garage....)
73, Nico
