How does it work? "Language Card" area Switches Bank 1 and Bank 2 here are the 4K banks at $D000-$DFFF. The remaining area from $E000-$FFFF is the same for both sets of switches. $C080 ;LC RAM bank2, Read and WR-protect RAM ROMIN = $C081 ;LC RAM bank2, Read ROM instead of RAM, ;two or more successive reads WR-enables RAM $C082 ;LC RAM bank2, Read ROM instead of RAM, ;WR-protect RAM LCBANK2 = $C083 ;LC RAM bank2, Read RAM ;two or more successive reads WR-enables RAM $C088 ;LC RAM bank1, Read and WR-protect RAM $C089 ;LC RAM bank1, Read ROM instead of RAM, ;two or more successive reads WR-enables RAM $C08A ;LC RAM bank1, Read ROM instead of RAM, ;WR-protect RAM LCBANK1 = $C08B ;LC RAM bank1, Read RAM ;two or more successive reads WR-enables RAM $C084-$C087 are echoes of $C080-$C083 $C08C-$C08F are echoes of $C088-$C08B
