Bzzt! If you were to attempt to call the slot ROMs in bank $E0, the screen
holes would also be located in bank $E0, unless the ROMs had yucky IIgs
specific code in them (i.e. not bloody likely). Accesses to the screen holes
are all in the data bank, which must be set to the execution bank when you
are running code like the slot ROMs that expects everything to be in the same
bank.
