     Yes. Quite a few DOS 3.3 programs will run fine under ProDOS with
no change at all. Unless you have some reason to believe a DOS 3.3
program will not run under ProDOS, it's worthwhile to just copy it to a
ProDOS diskette and give it a try. Since DOS 3.3 programs which do
direct writes can, possibly, damage a ProDOS disk, be sure to run any
risky-looking tests from a booted ProDOS diskette for which you have a
backup.

     If a DOS 3.3 program runs okay from a ProDOS diskette, you _may_ be
able to run it from hard disk without damaging files or directories. The
main thing you need to know is whether or not the DOS 3.3 program tries
to do direct sector writes to disk. Some ways to check for this are
described in the Csa2DOSMM.txt file in the newsgroup FAQs.

     If a DOS 3.3 program does not run from a booted ProDOS diskette,
you may be able to convert it for ProDOS. This is discussed in more
detail in the file mentioned above.

     The //e card in your Mac is not really an emulator. It is supposed
to _be_ an enhanced Apple //e (with a few exceptions, such as having no
Slots and handling the video through the Mac).

     If the Mac can download .dsk files or (download and uncompress
.dsk.gz files to .dsk files) AND if the //e can access the .dsk files,
then, you should be able to run DSK2FILE (from the //e) to convert the
.dsk files to diskette form via a diskette in the //e 5.25" disk drive.
