-program has almost full 64K for its own. A disadvantage is that kernal
-subroutines cannot be called (at least not in a fast and effective manner), so
-the runtime has replace kernal functionality.
+reserved for BASIC programs. Since there are no ROMs in this memory bank,
+kernal subroutines are either emulated or called by bank switching, which has
+the disadvantage of being slow compared to a direct call.
The default memory configuration for the CBM 510 allocates all memory between
$0002 and $FFF0 in bank 0 for the compiled program. Some space
