No, they are not compatible. You should not use Performa enablers with the
Macintosh operating system or Macintosh enablers with the Performa operating
system, since a particular system enabler may not have system resources that
the other operating system needs.
Also, do not put a Performa enabler and a Macintosh enabler for a similar
machine in the same System Folder, since this may cause unpredictable results.
