I am looking for programming assistance via email for the Apple //e computer. What I need help with is: The range from $C000-$CFFF. I know this is the slot area. I could use some sort of memory map. Bank switching, interrupts, etc. That sorta stuff. Any help is appreciated ------------------------------------------------------------------------------ Bruce!

What a particular address does depends quite a bit on your system configuration and the settings of some softswitches. Here's a basic outline of memory usage: 0xC000-0xC08F System softswitches 0xC090-0xC09F Slot 1 softswitches 0xC0A0-0xC0AF Slot 2 softswitches 0xC0B0-0xC0BF Slot 3 softswitches 0xC0C0-0xC0CF Slot 4 softswitches 0xC0D0-0xC0DF Slot 5 softswitches 0xC0E0-0xC0EF Slot 6 softswitches 0xC0F0-0xC0FF Slot 7 softswitches 0xC100-0xC1FF Slot 1 ROM 0xC200-0xC2FF Slot 2 ROM 0xC300-0xC3FF Slot 3 ROM 0xC400-0xC4FF Slot 4 ROM 0xC500-0xC5FF Slot 5 ROM 0xC600-0xC6FF Slot 6 ROM 0xC700-0xC7FF Slot 7 ROM 0xC800-0xCFFF Shared slot ROM space Note that the area from 0xC100 to 0xCFFF can be replaced in part or in full with system ROM code.
