Where to get the Kodak PhotoCD raw image dataset?
The dataset appears to be in the public domain, and has been posted at this site here.  

The pictures (24 in total) were originally released in 1991 on a CD.  The original media with the actual image data could be requested via interlibrary loan; here is a WorldCat link to the repositories holding this item. The CD was originally distributed by Apple Computer.  The raw version of the files do not appear to be available online.
