SCSI drivers and utilities for the 3B2 on 720KB 5.25” floppy diskette images.
Diskette images are straight sector-by-sector copies of original floppy disks. If you wish to write them to physical diskettes again, you can use the dd utility in UNIX or Linux, or the ImageDisk utility in DOS.
Physically, diskettes are double-sided, 80 track, 96 tpi DS/DD media using 250kbps MFM enoding, 9 sectors per track, with 3:1 interleave.
