 There are several programs for transferring disks from a PC to Mac .
Macindos , Macsee , and IMHO the best is Macdisk .
This is a description:
       macdisk.exe (249K)
        Mac Disk is a PC utility to read, write, and
        format Macintosh HD floppy disks. Bundled
        with an Ascii converter and a utility to edit the
        internal table. Contains a demo version under
        Windows and a shareware version. From Pierre
        Duhem. See ReadMe for additional information.

      macsq.exe (318K)
        Mac SQ is a PC utility to read, write and
        format Macintosh SyQuest cartridges on a PC.
        Contains a demo version under Windows and a
        shareware version under DOS.

 The macsq overcomes the problem of the non-MFM
800 and 400 k flopies if you have access to a Syquest
removeable.

 I can't find the URL for this but a search should easily turn it up.
Of course if you have a working Mac you can down load to a PC
The trick is not to uncompress on the PC but simply transfer the
uncompressed files and then uncompress them with Shrinkit .
The same technique works with the Atari ST
