High Speed

High Speed is a 1986 pinball game designed by Steve Ritchie and released by Williams Electronics. This game was based on Ritchie's real-life police chase inside a 1979 Porsche 928. He was finally caught in Lodi, California on Interstate 5 and accused of speeding at 146 mph. During its design, High Speed was jokingly called "High Cost" by some rival Williams designers due to its then-high production cost. The advances in the mechanical design that went into High Speed, coupled with the machine's popularity, led to many machines being kept in service much longer than was previously the norm. The play surfaces of the machine were not initially given as much attention, leading to many High Speed machines seeing service to this day in extremely worn condition. Williams rapidly addressed this issue by making mylar playfield covers available and later adding hard clear paint coats to their playfields. Canadian specialist Classic Playfield Reproductions is currently working on an officially licensed High Speed 13-color Reproduction Playfield, which is due for release in 2013.
