They are for external hardware, just like I/O1 and I/O2 on the Commodore 64. I/O2 is mapped at $9800-$9bff and I/O3 is at $9c00-$9fff. The tape fastloader "Vic Rabbit" maps its ROM to this area, and you could map RAM there as well (I rewired some RAM lines of my memory expansion there via diodes, in order to run the fastloader on the real machine).
