    Every VIC 20 expandable memory areas can be covered (also the I/Os areas), and BLK 5 can also be write protected!

    Dip-switch:

    1.) 8K= BLK1: $2000-$3FFF (8192-16383)
    2.) 8K= BLK2: $4000-$5FFF (16384-24575)
    3.) 8K= BLK3: $6000-$7FFF (24576-32767)
    4.) ON= BLK5 write protected
    5.) 8K= BLK5: $A000-$BFFF (40960-49151)
    6.) 3K= RAM1,2,3: $0400-$0FFF (1024-4095)
    7.) 2K= I/O2,3: $9800-$9FFF (38912-40959)
    8.) ON= enable expansion cartridge

    Total of +37K of RAM for your VIC20!

    NOTE:
    The 2K IOs area is important because is unusual,
    the perfect place for a speedloader like "RABBIT" for tape: Rabbit-sys38912.prg or for software-kernal simil-jiffydos: tokra_2K_SJload_$98.prg

    About how VIC20 manage memory areas in relationship at which areas are expanded
