POTHOLE (16K Spectrum)
by A Boyse
from Popular Computing Weekly (31 March 1983), page 15

In this program you, as a potholer, have to manoeuvre yourself down into a
cave, avoiding the rocks which block your way. The program uses the
Spectrum's ATTR function to find out if you have hit the side of the cave or
a rock, and it also uses Poke 23692,255 to fool the Spectrum into scrolling.
