I have a library of MasterCam posts.
You can go to the Trak Saftey, Programming, Operating & Care Manual
In mine is tells how to take a Fanuc 6 post-processor convert it to a ProtoTRAK post-Processor ( My Manual is for SM CNC )
Send an e-mail address and I will attach the posts in a zip files.
It is rather large, I will send the Fanuc post also
