The fourth Solid State game produced by Williams and the second to feature electronic sound. Tom Cahill, former Service Manager for Williams, told us that Disco Fever was the first game Williams engineered to have speech. A talking prototype was presented at the Chicago AMOA show. Production games did not have speech. Williams' 1979 'Time Warp' is the only other Williams game produced with the curved "banana" flippers. Their first game to have them, the 2-player Jai Alai, only got as far as the prototype stage and never went into production. Williams Daily Production Logs indicate a 4-player replay game named 'Super Jai Alai', approved for 300 sample games but none made, was deleted from the Log on Apr-3-1978, the same day that an approved 300 units of 'Disco Fever' first appeared on the Log. This is not a coincidence as both games had banana flippers, which means a decision was made to re-theme the game before production.
