This is one of the nice thigs about using DOS-XL (2.3 or later) with OSS's
Supercartridges (like the ACTION! and MAC/65 carts; these are the cartridges
with bank selects etc.).  The DOS actually comes in two forms, and you're
supposed to install one depending on the setup; one for supercarts without
XL machines (ie. the 400/800s) and the other for XL machines, on which
the DOS moves part of itself into the RAM hidden behind the OS, freeing up
some space.  So, using a supercart with DOS-XL on an XL machine one could 
probably be able to hide the cartridge under 4K only.
