Does anyone know if this has been completed or attempted? Something similar
to what DOS ImageDisk or 22DISK does? I would like to interface my 8"
floppy drives to a modern Linux box for imaging.
Insight is appreciated. Please reply directly as I'm not subscribed to this
mailing list yet.

Hmmm, some sniffing around suggests that these disks have a proprietary format.
The first cylinder is normal, but after that, the next 21 cylinders don't even
have a sector 0. I suspect there are 14 sectors of non-standard sizes, so this is
all going to be great fun.

If the discs were formatted with a WD17xx series controller, it's possible
that the first sector is too close to the index hole for the PC's floppy
controller to detect.
I have some old (20 years+) floppies that I'm trying to read. ddrescue
has got the good sectors off, so now I need to work on the problem
Will fdrawcmd let me ignore CRCs and just got whatever is there?
Is there any way to play with things like precomp? Lots of my disks are
OK at the start but hard to read at the end.
Any/all advice is very welcome.
