"The Last Ride", George M. Ottinger 1873. A Pony Express rider
The telegraph work with different principles from the computers except the Baudot Multiplex that does not use the Morse code but, forerunner of modern computers, the first digital code of ... 5 bytes. It's a milestone of telegraphy, first used to link France - Italy in 1877 and that in 1894 allowed "real time" operations between the stock exchanges of Milan and Paris. Baudot code developed in the modern ASCII. More about Baudot and his Multiplex at Codes that Don't Count.
It's very rare but I have fortunately found a complete and running unit. More on telegraphs in my Homepage.
