This applies to the Apple II, Apple II+, Apple IIe, and Apple IIc.
The Apple FORTRAN compiler is protected and cannot be copied. A Bad Block
scan of the FORT2: diskette will show blocks 30, 31, and 32 as bad. Any
attempt to "fix" these blocks will ruin the FORT2: diskette. See your local
service center if your FORT2: diskette doesn't work.
