Start:

1. Set $00F1 to $00 to ensure the CPU is in decimal mode
   

2. Set up the interrupt vectors for BRK:
   $17FA 00
   $17FB 1C
   

3. Load the KIM1541 Program (or burn it on an EPROM)
   

4. Loading and saving uses the same procedure as loading and saving to tape:

   To save:
   

   1. Save start address (low/high) in $17F5, $17F6.
      
   2. Save end address+1 (low/high) in $17F7, $17F8.
      
   3. Write Programs ID ($01-FE) in \17F9. (this will be the filename)
      
   4. Run address $2148 to save to disk
      

   To load:

   1. Write Programs ID (the name on the Floppy - $01-FE) to \17F9.
      
   2. Run address $2000 to load from disk.
      

Update: I've also changed one version to be loaded to $A000 for my ROM Module
Update2: I simply forgot to show how to wire things:

Have fun,
