Cassis dvd finder

There was proprietary software that came with the Cassis dvds but apparently it ran in a 32 bit operating system like Windows 95. The discs themselves can be put in a more modern Windows laptop or desktop and the tiff files can be accessed by navigating to the directory paths shown here. There were USAPat and USAMark cds released prior to 2000 whose images are in a proprietary yellow book format. These can be converted to tiffs by uploading them to this site.
