Ah, right: IP = Intellectual Property. I guess they might just be worried
about people stealing their design too, plus, if they can get customers to
accept not having schematics for whatever reason, they get a monopoly on
repairs.
Seems like I'm going to have to resort to reverse engineering - hope the pcb
doesn't have more than 2 layers!
