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?
