(Envisioning something hanging off a Raspberry pi for a moment :)
Does anyone know of any adaptors to fit a
"modern" drive (be it IDE,
SCSI, ATA, CompactFlash etc) into a machine with an ST-506/412
interface?
That... would be quite the task. ?The ST-506 and cousins directly
output the raw flux transitions as their data, so you'd need an
emulator which spit out the data as repeated cylinders, I believe.
Trying to interpret incoming data as low-level formatting would be
another matter entirely. ?You'd probably be better off emulating
the interface to the drives (e.g. emulate an MFM controller).
On the other hand, it's not *that* different from emulating a
floppy drive, which people have done successfully. ?It wouldn't
be impossible, but I imagine it would take some thought to get
it right.
