Publisher's Catalog John Allen works his machine language magic again, bringing all the thrills of championship bowling to your TRS-80 model I or III. From one to four players participate, and the program automatically senses the skill of each player. Beginners can simply position the ball and "roll" it while more skilled players can vary the force, curve and spin as it heads for the pins. All this--plus 3-D graphics and sound effects--adds up to a realistic and thoroughly challenging bowling game.
