About handling of floppy disk
The data and program for this machine, which are managed by PT basically, can also be saved to and
loaded from a floppy disk if necessary.
In order to protect important data and programs, this section
describes the instructions for protection and handling of floppy disks.
NOTICE
It is only 3.5-inch 2HD (1.44 MB format) floppy disks that this machine can use. The
2DD type cannot be used.
1 Backing up Data and Program
A floppy disk is a compact and lightweight storage medium that is convenient for storage and
carrying; however, the stored data may be erased or may not be loaded owing to an improper
handling.
Be sure to back up the program and data in order to guard against the loss of data. Backup
means making an identical copy of a floppy disk.

For information on how to back up, see the disk copy procedure under file operations.
