I actually have an older Apple CD, but none of the demo CDs. I highly recommend making an image of the Apple CD 300 disc for preservation purposes, I can't imagine copyrights getting in the way of a demo disc, especially in this day and age. There are simply too many acquisitions and technology changes in the personal computing industry.

There is an archive location which contains loads of old mac software CDs at https://archive.org/details/software

If you prefer to share with the people here, you could simply post to Skydrive or rapidshare.
