Sodick wire EDM machine retrofit

Find the circuit diagrams for your machine showing how the control frame computer connects to the generator and gets feedback from it on when there is a short between wire and workpiece then work back from them?
Henk has done the axis/wire feed interfacing already, but doesnt have a original generator to work with.

Did you ever get your machine working? My three A280s are now all dead and I am now faced with an immidiate decision whether to tackle a retrofit project.or invest in a different machine.
