Here is a very rare one from my Autodesk historic collection. CAD Cameras 1.0 was a utility to convert paper drawings “digitizing to AutoCAD using a flatbed or fixed-distance scanner in 1985. I actually have the entire package with the 5.25” floppy disk. Perhaps the floppy disks have good data to run it on an old PC system, but most likely not as they are 35 year old magnetic floppies and time and electronic interference are not kind to the data integrity.
