There was a major upgrade in 1983 that included a new control system, new sound system, and additional speakers and houses.

 

New computer control system 1983. Used a Radio Shack (Tandy) TRS-80 to create the choreographed programs.

The music and control channels were recorded via modem to a 4 channel reel-to-reel tape recorder.

Two channels for music, one channel for a timing reference signal, and one channel for ASCII (text) commands to the PLC to change water levels and lighting. The PLC “listened” to the tape via a modem and an ASCII interface module.

Before this upgrade the control system was a paper punched tape and a custom wired wrapped relay panel.

Notice the banks of incandescent lights to illuminate the water modules.

These used aircraft runway lights and colored (red, blue, & amber) filters in front of them.

The three banks of lights in front of each of the seven water modules were replaced with two LED units per water module in 2013.

 

Amplifiers upgrade in 1983. Ten 800 watt amplifiers. 8000 watts total.

Here you can see the new speaker houses (left and right). The existing (1962) speaker house is in the middle.
