like let's return to the late 19th century where the time we were focused as we are today on speed and one goal to improve speed was to design a machine which allowed the operators to input letters which we did think about as primary symbols that have the machine automate the lower level signaling events such as post electricity we can call secondary symbols the machines can be driven by some clock source allowing you to generate increased size and rapid whole stream which presumably would run much faster than any human hand and one great example of this was the but dole multi-plex system and the design was put into service in 1874 the minute built of the same conceptual ideas we've seen in the shutter telegraphic consisted of five keys which could be played in any combination the niqab it as a chord the no the needs combination would represent a unique message with five nodes bg their honor of you can play too to the power by for 32 different chords the code assigned the 32 different chords to each letter of the alphabet with the leftover used for carriage returns new lines and spaces the new so the operator with
