1 Introduction

GamePlan made pinball machines from 1978-1985. The first pinball machines were cocktail size. The first full-size pinball machine was SharpShooter in 1979 that was designed by Roger Sharpe. System-wise, GamePlan kept the same Z80 system throughout their pinball career. The early cocktail pins used the MPU-1 board, and the full-size machines used the MPU-2 board. The only difference is the amount of RAM. GamePlan used individual driver boards for the solenoids (the SDU-1 board) and lamps (LDU-1 and LDU-2 boards). The displays on all GamePlan machines are LED displays and hold up quite well because of this. The sound system did change frequently, starting out with Chime units in the early cocktails, to solid state "hard-wired" sound boards, to sound boards that were designed using the Motorola 6802 processor (MSU-1, MSU-2).
