It's a stock standard Western Digital WD1010 or WD2010 format. 512 bytes
per sector, 17 per track but only 16 used (the 17th is a "spare" sector).
DiscFerret can image the discs, but the MFM decoding is spotty. Mainly
because the software PLL emulation isn't quite right...
I don't have another UNIX system with an MFM controller right now
I doubt you'll find a controller that can grok the low-level format.
Phillip may know more. What I was thinking of was squirting
'/dev/rawdisk' somehow out the
ethernet.
That'll be difficult if the system is running. The disk surface will be
changing as background tasks move stuff around. I'm not certain you can
boot it in single-user mode...
Booting off the Foundation "Floppy Unix" set (floppy boot and floppy FS)
is one option, but you won't have anything to transfer the data across.
You'd have to modify the Floppy Unix disk somehow to add Kermit or
umodem (UNIX PC's xmodem) and stty.
