AT&T Unix PC floppy images #279

They just use a standard 10 or 8 sector 5.25in IBM floppy with a cpio image on the disk usually instead of a fat filesystem.

I see other people are having some success with reading similar disk formats so I'll have to give this a try and upload a a few images for you to inspect here once I've assembled a fluxengine. Would it be possible to detect the number of sectors if you know the machine type ahead of time?

I'd really like to have a tool to image disks and get data onto and off of my system that way (probably link it up via serial later after I get some software onto it).

Yes, the IBM reader (fluxengine read ibm) will autodetect nearly everything and figure out the format. The one thing it can't know is whether the start sector ID is 0 or 1 --- you'll need to set this via --decoder.ibm.sector_id_base. Once determined, adding a profile for the Unix PC is easy; see src/readables/acornadfs.textpb. (In fact, if the start sector ID is 0 you can probably just use the acornadfs profile.) Let me know if it works; adding support for this would be great!
