A gaming machine system comprises a game cabinet, a processor, and an audiovisual effects system. A predefined group of equipment is selected by activating individual capacitive sensors. A preferred embodiment includes a redundant architecture having a signal bus for coupling the microprocessors to the level-2 or level-3 cache memories in which the signal bus includes a programmable selector circuit for bypassing defective microprocessors or defective level-2 or level-3 cache memories. The row of FLADE fan blades may be disposed between rows of variable first and second FLADE vanes. The remaining portion of the fourth dielectric layer forms corner spacers. The slotted member presents a reduced area through which heat or sound may be conducted and slots in which insulation is received, both increasing resistance to heat and sound transfer.
