In answer to a number of inquiries, the 50 backup floppies are 3.5” floppies
that were created with Colorado Backup.  I don’t know which version, and
from what I read in various forums via Google, later versions of Colorado
Backup were unable to read backups made with earlier versions.  So
whoever reads them will probably have to point various version at the
disks until one of them works.  Certainly no current software will read
any version of Colorado Backup’s format.

There’s also the likely problem of the media having aged out.
