Quantity six Memorex 720 KB, single-sided 3½-inch diskettes. Early 3½-inch floppy disks, probably made in 1984 (first digit of lot numbers may indicate year manufactured). Although they do not look exactly like most of the 3½-inch floppy disks made throughout the 1980s, 1990s, and beyond, they are readable in 1990s and 2000s diskette drives. Despite these being marked as "1 sided," they format 720 KB in a typical double-sided diskette drive.
All six diskettes were readable in my diskette drive, but I was only able to format three of them (the last three noted in the pictures). The first three may be usable, but I cannot confirm this with my diskette drive. One of the last three, formatted diskettes has some broken plastic around the write-protect tab (last picture).
