Quoting Gareth Murfin:

"As far as I'm concerned they have been public domain for the last 3 or 4
years since Amiga Future had them on their coverdisks and website (with my
permission). But recently people keep asking me how to get them, so I simply
downloaded the ISOs from Amiga Future's site and included them here."

Note from Aminet administrator: thanks to earok and nittamituaki for pointing
out that this is now frely distributable.
