There are two main manuals,"Reference and User Guide" and an installation manual. Plus a Galil command reference and Galil card installation manual. There may also be a separate AS3000 CAM manual. On my software there is a lot more available in "search for solutions". Plus, the are several other files of information that you can open in a word processor on detailed things like how to install an IO card. all the Galil manuals can be downloaded from galilmc.com
I know Camsoft gets $500 a year for support and maintenance(new software). Well worth it for the best support around. My understanding is you basically have to pay up the back years if maintenance lapses.
