HP-71 trouble - ZOleg - 05-14-2009

I have HP-71B 2CCCC with FORT/HP41 rom, Surveying rom and +32Kb ram mounted internaly in calc and 128Kb ram, 64Kb ram and HP-IL in ports.

I typed and run SYSTCAT program from HP-71 Users Library Solution Utilities book, but after few seconds i get this error:

Err:L210 File protected

I think this is FORT or Surveying rom memory area.

How to get access to protected memory area in HP-71?
