Crumar Musical Instruments User Group.

hi, i'm from Italy and i've a crumar Trilogy. i'm trying to 
understand how does it work beacause mine don't work well.
Now i'm tryin' to study the boards that controls the keyboard and 
the poliphony of the synth but i've only reached some general 
information about the components(es: IC like TOS ,logic port and so 
on)and the paraphonic approach of the synth. Please can someone send 
me some schematics for the trilogy????
