I disagree.

First, the Apple IIGS emulator Bernie II to the Rescue
for Power Macintosh can easily access IIGS programs
stored on an HFS CD-ROM.  Some Apple IIGS
programs can't run until installed on a large volume
(hard drive or CD-ROM) so disk images are not always
useful.

Second, the Apple IIGS' OS, GS/OS, can easily handle
multiple file systems.  It can read old Apple II DOS 3.3
or ProDOS on the one hand and ISO9660 CD-ROM
format, MS-DOS FAT, or Macintosh HFS on the other.

Thus, the easiest way to archive your old Apple II
software is to store them on a IIGS hard drive partition.
This can be a ProDOS 32MB partition or an HFS
partition of easily 1GB or more.  But the easiest way
is to connect a 100MB Zip disk to the IIGS and copy
(or ShrinkIt GS archive) all your disks to the Zip disk
formatted as an HFS volume.

Then take the Zip disk to the PC.  Then use your
CDR burner to duplicate the Zip volume onto CD.
Sure, you waste 500+ MB of the CDR's space, but
it is easier.  Of course if you use a 1GB Jazz drive
partitioned to 650MB HFS instead, you won't waste
any space.

Or you can simply use MS-DOS FAT formatted Zips
or Jazzes because the IIGS can write to these using
the MUG! desk accessory.

When you burn the disc, however, you will want
to use either ISO9660 or HFS because these are the
two formats that the IIGS will recognize on CD-ROMs.

Now if the Apple II program is 16-bit IIGS specific,
then that program can actually be launched from
and run from an HFS CD-ROM, so you would
not mess with disk images at all.  Simply copy your
IIGS program files to the Zip or Jazz, use the PC
to burn a copy on CDR, then take the disc back
to your Apple IIGS CD-ROM drive and run the
programs right off the CD-ROM!

Note that Macintosh can easily read these ROMs
as can Windows 95 with the right software and the
IIGS emulator for the PowerMacintosh can use
these files.
