I was having trouble with the links on this page: www.flyingpig.com/support/hog3/documents/manuals.shtml But they all seem to be working now.
Though the link from the Full Boar page titled "View Wholehog User Manual and Full Boar TechNotes" takes you to a page for Hog 4 manuals, instead of Hog 3: www.flyingpig.com/support/hog3/downloads/FullBoar.shtml
