The Macintosh can archive Apple II 3.5" disk with Disk Copy, but I prefer
to use an Apple II native archiving format for all my Apple II disks.
I use ShrinkIt v3.4 to create both 5.25" and 3.5" Apple II compressed disk
images, and transfer the files over a serial link to a PC. There they can
be recorded onto an ISO 9660 CD-ROM. The files can be transferred back to
an Apple II and converted to a real disk again. I have transferred over
25MB of Apple II disk images this way.
On the PC the ShrinkIt files can be manipulated with Nulib and Mapper to
create .DSK images to use with emulators.
