Appearantly Hyperion and Fr...friends, are the ones that sit with OS3.1 sources at this point.
Anyways, sources are not that important as getting rid of the "piracy" stigma that comes with copying around classic OS and kickstarts for use with UAE, minimig or whatever. I personally have no track of how many legal copies I have of the various AmigaOS incarnations, or how many kickstarts or kickstart files I have, or even where I have them. I also have at least a couple of OS3.5 CDs that also come with 3.1, and a handfull of OS3.9 CDs that came with OS3.5. Some of those CDs are quite shady looking even though they no doubt are original. The last few times I bought kickstarts from "well known and reputed amiga dealers", I noticed that EPROMS were used - hardly originals. Not to mention all the magazine CDs that came more or less with full OS3.1, and likewise CD32 and CDTV CDs that also came with full OS install on CD.
I suppose it's time I just put what I have on my website already, just to see who will jump up and claim moral highground, or worse... ownership (hah!).
