Wow, the files shared with me are still on dropbox after 6 years. I looked just to verify how they were packaged to see if they are done so in a way that preserves the resource fork; they are in zip files, which I am grabbing again. But a quick perusal seems to indicate that things in this collection are .sit files, which makes sense to preserve the resource fork if you were distributing this stuff via FTP at the time. This is pretty cool stuff.
The entire collection is 25GB, which is huge considering that in 2000 most computers had a hard drive in the 10GB capacity range.
