Not easily possible. With the HD disks and, assumably, these new 2.88 meg drives the information is recorded at a higher bit density (clock speed) than Amiga's are able to handle. Or, more properly, designed (off the shelf) to handle. Since, on the Amiga, the floppy disk decoding is done with the Custom Chips they would have to be fast enough to be able to decode the higher clock rate on 1.44 or 2.88 meg disks. On other systems, at least ones which use standard floppy disk controllers, they have to use one which can handle these higher clock rates. One could fairly easily design a plug in board which contains a floppy disk controller. This would require a device driver (fdc.device?) and changes to `format' so it knows about this new format. (Or is it that format simply sends a FORMAT-DEVICE packet to the device driver?) This wouldn't really be any harder than any other plug in board design. I hope this answers your question. -- <- David Herron, an MMDF & WIN/MHS guy, <- Formerly: David Herron -- NonResident E-Mail Hack <- <- Sign me up for one "I survived Jaka's Story" T-shirt!
