The protection is based on Sector 365 ($016D). The Basic file "BOOT" in disk image "Atari Book Keeper - Data Entry.ATR" has the protection code (sector #140 on the disk).( line 32760 in the BOOT file).

Attached is unprotected "Atari Book Keeper - Data Entry.ATR" PRO disk image that was provided by AtariGeezer

 

Please note that the Software was not tested further

That's amazing, thank you!

It boots in an emulator.  I'll write down a real disk and test tonight. 

Any chance you can do the "Reporting.pro" one too?

The company code should be : BENSON as stated in the Sample Data Base disk.

I removed the protection, but did not thoroughly test the software package.

The unprotected  "Atari Book Keeper - Reporting.ATR" disk image is attached.

As I recall, changing the seek routine to look for sector 0 instead of the designated bad sector bypasses this kind of protection.
