Things are not as easy as they seem:
Amiga Inc. claimed to inherit the 1.0 thru 3.1 back from Gateway. Wheter this is true, has been a subject of discussion a long time before. The results are inconclusive, there are no proofs of anything, only claims.
Amiga Inc. partnered with Haage & Partner to produce 3.5 and later 3.9. Basically all the funding and developer effort was managed by Haage & Partner, who signed a contract in which Amiga Inc could buy back the 3.5/3.9 code which was based on 3.1. Fact is Amiga Inc. never bought back the 3.5/3.9 code.
Then as part of these more recent lame trials between Amiga Inc. and Hyperion, Amiga inc. agreed to grant Hyperion exclusive worldwide distributor rights for AmigaOS 3.1
So to sum up:
1.Amiga Inc. claims to have legally inherited all AmigaOS development upto 3.1
2.Haage & Partner + Amiga Inc (That is, in the exclusive case of Amiga Inc, if you believe point 1 is true) both own 3.5/3.9
3.Amiga Inc granted Hyperion a worldwide exclusive distribution rights for AmigaOS 3.1 (The validity of this right depends on point 1)
I wonder how we could get your work on Boing Bag 3 and 4 into official updates...
