A dispenser controller is connected to an existing conventional fountain dispenser to form a unitary currency/card operated dispenser system. The dispenser system includes a support element which supports the dispenser controller and separably attaches the same to the fountain dispenser. The support element includes a platform having a first side and a second side. The first side is disposed beneath and connected to the dispenser with the second side extending outwardly therefrom forming a support shelf. The support element further includes one or more apertures formed in the first side for receiving one or more legs of the fountain dispenser. The support element may further include one or more support legs provided at the second side. A dispenser controller cabinet is mounted on protruding shelf formed by the support element's second side.
