This listing is for the Claris ClarisWorks software for the Macintosh. This software comes on 6 - 3.5” Floppy Disks. There is no serial number with this software.There is not a version number on any of the Disks, but the copyright date on the label says 1991, so maybe this is version 1? Just guessing.I use my Macally USB Floppy Disk Drive For the Mac to test my Floppy Disks. However, this Disk Drive can only read HD High Density Floppy Disks. Double Density Disks can only be read on Apple branded Floppy Disk Drives so I’m listing these items as parts only.All of these disks have been stored in floppy disk boxes for many years in a closet.Please look at the Photos. They will show the item you will be receiving,
