CASTLES OF CARMAIN (16K ZX81)
by John Wood, Wednesbury, West Midlands
from Your Computer (November 1984), page 183

 This is a program for the 16K ZX-81 called the Castles of Carmain. All the
castles must be destroyed by typing in the angle of elevation, followed by
the velocity of the cannon ball.

The castles appear randomly on each game but are always possible to hit.
The cave is also drawn randomly.
