Pillbox was an early graphical artillery duel game. In addition to being sold as a stand-alone program, it was published as a type-in program in the first issue of Softside magazine.
Softside Magazine - October 1978
Several version of Pillbox have been published by Author Gene Perkins. This particular version, which awards a victory to the side which first scores hits on five of his opponent's placements, was prepared by the author at our request almost literally at the last minute.
The play of the game is deceptively simple. The computer draws the "battle ground", which consists of two gun placements separated by a forbidding mountain. Each player controls the angle of fire (0 through 90 degrees) and the muzzle velocity of the projectile. The configuration of the "Battlefield" is never the same, and your first shot or two usually winds up either hitting the mountain, or overshooting your opponent's pillbox.
The program runs on either Level I or Level II 4K TRS-80 microcomputer, and we think you'll find it's Fun/Keyboard Time Ratio quite satisfactory.
