Truck Stop and Atlantis: 6803 games built by Williams

After Williams bought Bally, Truck Stop (#2001, prototype name Ramp Warriors) and Atlantis (#2006) kept the 6803 CPU board and 9-segment displays but used a Williams System 11B sound board D-11581 through a small interface board, plus a System 11 50 volt flipper power supply. Neither uses the keypad. Atlantis renumbers the CPU board chips to the Williams scheme and keeps the 6803 fuse board.
