have some programs that are not version 7.0 compatible that I'd still like<BR>

running system software earlier than version 7.0 and use those programs?<BR>

  <div class="attr SUMMARY">
Yes.  You can start up from a system software version 6.0.X startup floppy<BR>
disk, provided that the Macintosh doesn't require version 7.0.1 or later to<BR>
run.  The Macintosh Classic II, Macintosh PowerBook series, and Macintosh<BR>
Quadra series do not support system software version 6.0.X.<BR>
<BR>
Note<BR>
----<BR>
Version 6.0.X does not recognize the version 7.0 desktop file.  When you<BR>
first start up from the version 6.0.X floppy disk, a dialog will appear<BR>
reporting that the version 7.0 hard drive is damaged and asking if you want<BR>
to repair it.  (Your hard drive is not damaged.)  Click the &quot;OK&quot; button, to<BR>
create the version 6.0.X desktop file.<BR>
<BR>
The next time you start up from the version 7.0 hard drive, the system<BR>
software will update the version 7.0 desktop file for any changes that were<BR>
made during the version 6.0.X operation.<BR>
