OK, I'll see what I can do. You left some Intel floppies of them out here, and
I've got some Amigo OS disks that are pretty important to image.
Guess I need to get the Diskferret set up ;-)

No, but since it had no trouble with the HP M2FM, I'm starting to
think that perhaps my PLL code is OK and the drive used to read those
Intel disks might have been suboptimal.
I need
Is it doing better on Intel M2FM now?

I'd still like to get a 9885/9895/7902 M2FM

The Amigo used the 7902A floppy drive, which supports the same formats
as the 9895A. This includes HP M2FM, single or double-sided, and IBM
3740 FM single-sided

Which was the Amigo?
FWIW every 5.25" and 3.5" HP drive unit that I've seen (and the
internal drives on the 9826 and 9836) use a Western Digital or
compatible disk controller chip. The low-level format (sync

I have a kryoflux preservation stream but so far can make no sense of it.
