Eric, the reason Blesser doesn't see the System 7.0 System file is that
the creator has been changed!  Under System 6.0, the System file is a
'ZSYS' file.  Under 7.0, it's a 'zsys' file.

Since Blesser looks for a file of type 'ZSYS', it doesn't see System
7.0. However, 7.0 doesn't seem to care a bit if you change it's type to
'ZSYS'.  This let's Blesser work just fine.
