Apple II's Slots



    We can live to use Integer BASIC without using Applesoft BASIC.  It 
means that Integer BASIC does not use $D000 through $DFFF.  Apple II's 
motherboard is limited to 8 slots which they use $C100 through $C7FF.  If we 
hack to modify Apple II's motherboard to expand from 8 slots to 16 slots. 
Extra 8 slots would use $D000 through $D7FF.
    If it works according to my desire by doing clever hacker, I doubt that 
softswitch may be modified.  It is like I/O control from $C080 through $C08F 
such as I/O Disk.  It would use LDX #$60 and LDA $C080,X which they map to 
$C090 through $C0FF so they cannot be remapped to $D000 through $D0FF.  They 
have to add new softswitch from $D080 through $D08F which they can be 
remapped to $D090 through $D0FF.
    What do you think?  It might be a problem with compatibility issue such 
as 16K RAM switch.
