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!
