Technical guide - thank you Speleo from Silicium forum
To transfer the ascii programs provided by hebdogiciel.fr to the X-07 use Marcus utilities and the following syntax :
bas702.exe -w file.txt file.wav
Then, you vave to read the wav file with an audio file reader like audacity and plug the ear output of the pc to the X-07.
To plug, use the Canon XC-910 cable.
