The AT&T 3B2 Software Archive

This is an archive of software for the AT&T 3B2 series of computers.

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.
