Truck Stop (Bally 1988)
This is an interesting machine. It is the first game after Williams / Bally merge.
This shows when looking at the inside. CPU board is a Bally 6803 model. Sound board
however is from Williams Sys11. On the playfield, upper flippers are made with Bally
mechanics, and the lower are Williams style. One playfield plastic shows a sign of
merging roads with text "Williams/Bally MERGE".
The game was originally planned to be released as Ramp Warrior but the name
changed to less aggressive Truck Stop.
