At some point after RKO purchased WAXY (and it may have been before they moved to their E. Sunrise Blvd. palatial facility), they installed an enormous cart-based automation system called "Cuerac". It was one of only a handful of such systems worldwide; constructed in Australia, I was told.
The Cuerac consisted of three ceiling-high units, each containing a rack of hundreds of carts of music, commercials and disc jockey voice tracks. Chain-driven robot arms, programmed by a rudimentary computer system, would grab carts and insert them into one of about a dozen cart players. Most of the time.
Much like Musiconradio's experience in Key West, the WAXY jocks would record a show's worth of talk content -- song talkups, raps into commercial breaks -- cut by cut, onto an 8.5-minute cart. Screw up one rap -- and you had to start over.
Most WAXY veterans remember the Cuerac for its repeated malfunctions -- firing the wrong songs, jamming the carts into the players, missing the players entirely. Cuerac was ultimately abandoned in the early 1980s, and gave way to a staff of human board-operators 24/7.
Weekday airshifts finally went live -- though Rick Shaw continued to voicetrack at least a portion of his afternoon show on reel-to-reel, fired manually by the board-ops. Cuerac still occupied the WAXY master control room, serving as a very expensive cart rack until dismantled by Metroplex when they bought the station from Ackerley in 1992.
Weekends remained voice-tracked (but with live operators -- and a live overnight newscaster!) until September 1987; I may have been the first regularly-scheduled live weekend talent on WAXY. Eventually most of the weekend went live as well, with part-timers; Dick Bartley via satellite and a taped Sunday night oldies show with Rick Shaw were the only non-live dayparts by 1990.
