Yes, but the pointers high byte is hard wired to $01, so you can only use
the LO-Byte
=> adressable stack area: $0100-$01FF
yes, and that's the reason why the 128 bytes of ram you have are mapped in
twice:
- once at 0x0080-0x00ff, so that the ram can be accessed with zero page
accesses.
- once at 0x0180-0x01ff, so that the stack can be used, because it is
assumed to be in page 1.
> Where is it ?
Inside the microprozessor
no, it's external ram. in the case of the 2600 it's in the 6532.
>at the end of the 128 bytes of ram ?
yes.
