Not only that but the examples are updated to 4.x while the former examples are not available anymore...
From the front page, "This is the AmigaOS Documentation Wiki. Here we collect all information for users and developers of AmigaOS version 4.0 and beyond."
If you want material prior to version 4 of AmigaOS then you will likely need to talk to Cloanto. Cloanto has been buying up all the rights to previous versions of AmigaOS and Michael is very interested in preservation. Michael has been pushing the preservation idea at every single Amiga 30th event this year so I'm surprised you guys missed that.
Back on topic, I think some people's dogmatic idealism is getting in the way of getting things done. A-EON is doing a fantastic job of getting new software products to market by paying developers so don't complain when they want to protect their copyright at the same time. If you don't like it, stop the endless talking and start a bounty to buy the rights from A-EON and make it "free" or get out of the way because they aren't slowing down for a few hippies.
