Regarding ImageDisk and Linux - all I see needed to do it properly are
some enhancements to the floppy driver - the ability to configure for all
possible formats the 765 can do (if Linux does not do this already which
I think it might), and the ability to do track-by-track analysis. These
things would be easy to do in the driver. Then the "ImageDisk" program
becomes a simple application which makes IOCTL calls to analze the disk,
and configures the controller, and then simply reads sectors off and writes
the .IMD file.
Just a quick check of devices.txt show these floppy formats currently
supported on a stock SuSE install

(1) Autodetectable format
(2) Autodetectable format in a Double Density (720K) drive only
(3) Autodetectable format in a High Density (1440K) drive only
NOTE: The letter in the device name (d, q, h or u) signifies the type of
drive: 5.25" Double Density (d), 5.25" Quad Density (q), 5.25" High
Density
(h) or 3.5" (any model, u).
Filesystem support is another matter.
