got an answer! p was half right.
this is his literally response:
''its a mutation of axón, the connection between nerve cells and action*. that was the idea. the word had to take part of the computer program name and had to be five letters to leave three spaces for the numbers. back then we were in the DOS on PC** days and the names had to be eight characters max.''
* action in spanish is acción, the double cc is pronounced like an x.
so axón + acción = axxón
** the online magazine was made in the 80's
