Disk: Victor 9000

The Victor 9000 / Sirius One was a rather strange old 8086-based machine which used a disk format very reminiscent of the Commodore format; not a coincidence, as Chuck Peddle designed them both. They're 80-track, 512-byte sector GCR disks, with a variable-speed drive and a varying number of sectors per track --- from 19 to 12. Disks can be double-sided, meaning that they can store 1224kB per disk, which was almost unheard of back then.

FluxEngine reads these.

Reading discs

Just do:

fluxengine read victor9k

You should end up with an victor9k.img which is 774656 bytes long. if you want the double-sided variety, use --heads 0-1.

Big warning! The image is triangular, where each track occupies a different amount of space. Victor disk images are complicated due to the way the tracks are different sizes and the odd sector size.
