I've tried to find them to no avail. I'm guessing the box sets just aren't made anymore, but I figured it's worth asking in case there's some obscure one out there somewhere.
To clarify, I'm looking for a more recent Linux version. I know the older ones can be found on auction sites and the like.
I'm not aware of anything. Why are you looking, maybe there is something similar out there.
Mostly just purely nostalgic reasons, computer software in boxes.
