Same with the Atari, typically a fixed block between $A000 and $BFFF (8K) and then switch in block by bank # into $8000 -> $9FFF. What you do with the bank, ie. copy it to RAM I supposed does make it a kinda ROM disk. The NES models were far more flexible, e.g. fixed 16K at $C000->$FFFF and then switch blocks into $8000->$BFFF, and that's just for code!
