3B2 Software Archive

The 3B2 Floppy Disk Archive

This is an archive of software for the 3B2 computer on 5.25” 720KB floppy disk images.

These images are straight sector-by-sector copies of original floppies. 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 two-side 80 track 96tpi DS/DD media using 250kbps MFM encoding, 9 sectors per track, 3:1 interleave.
