Select a direction and hit the "Periodic Check" button. If you encounter treasure, at your discretion you may press the "Container Defense" button to see how it is defended. The third and fourth buttons are not from the original Appendix A in any way, but I thought it would be appropriate to supplement with the standard empty room list and some generic monsters, if you don't have an appropriate list at hand. You will have to come up with your own magic items if any are rolled.
