RE: 41CL MMU Backup
Here is my revised procedure. It still leaves me with a locked calculator after MMUEN:

Code:
Save Configuration to Flash Memory

        [ALPHA] 800>3F0 [ALPHA]              Copy page 800 (Main Memory)
        [XEQ]  [ALPHA]  YFWR  [ALPHA]        to page 3F0         
                                        

        [ALPHA] 804>3F1 [ALPHA]             Copy page 804 (MMU Config)
        [XEQ]  [ALPHA]  YFWR  [ALPHA]       to page 3F1         
                                    

Restore Configuration from Flash Memory

        [ALPHA] 3F1>804 [ALPHA]            Copy page 341 (MMU Config)
        [XEQ]  [ALPHA]  YMCPY  [ALPHA]    back to page 804.
        [ALPHA] 804040-0000 [ALPHA]        
        [XEQ]  [ALPHA]  YPOKE  [ALPHA]    
 
        [ALPHA] 3F0>800 [ALPHA]               Copy page 3F0 (Main Memory) 
        [XEQ]  [ALPHA]  YMCPY  [ALPHA]    back to page 800. 
                                    

        [XEQ]  [ALPHA]  MMUEN  [ALPHA]        Enable the MMU
