The low level format of Macintosh and IBM PC-clone 1.44 MB floppy disks is
the same; therefore, it is possible, but probably not trivial to do with
the images that Apple has on their FTP site. I once downloaded the
Macintosh system software variants that Apple makes available, then used a
Mac to make disks from the image files, then made images of the resulting
disks using dd (on a Linux box). The resulting images can be copied back
to floppy disks using dd (or rawrite under MS-DOS). Kind of a handy way
to avoid needing a working Mac to make the disks to get a Mac working.
Unfortunately, I don't think Apple allows redistribution of their OS by
third parties, so I've kept these images to myself.
Does anyone know the format of Macintosh Disk Copy 4.x images? If this
program is doing the obvious thing and simply storing a raw dump of the
disk's contents in the data fork, then it should be possible to make
Macintosh disks from these images using rawrite or dd, provided that a
means exists on your platform of choice for extracting the image file from
the compressed archive provided by Apple.
Note that 400k/800k Macintosh disks cannot be written to or read by IBM
PC-clone hardware, so you're out of luck if your Mac isn't equipped with a
DS/HD (or FDHD, in Applespeak) drive.
