The reference to "Amiga OS Release 4.0" in this material is a reference to the v42 version of AmigaOS planned by Commodore. It is not related to the v50 version of AmigaOS developed by Hyperion Entertainment CVBA which is the existing AmigaOS 4.0 for PowerPC.
May I ask how Hyperion can claim copyright to something they may or may not even have a license to?
