Disclosed herein are herbicidal compositions comprising a synergistically herbicidal effective amount of aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof, and triclopyr, or an agriculturally acceptable salt or ester thereof. This reduces the amount of space that is consumed in electronic devices in which the assemblies are installed, which allows the electronic devices to be made smaller in size. The substrate is spun within a bowl such that an excess amount of photoresist is propelled off of the substrate to an interior surface of the bowl. In another aspect in accordance with the invention, the exercise console includes a substantially fixed array of buttons incorporated into the housing. The system can also be used in cooperation with Internet Web service for reporting, accounting, information services, and user interaction.
