A gaming machine with serial communications between components of the gaming machine and a controller. A power bus distributes power to the componetns attached via quick connects. High Frequesncy (HF) communications are transmitted over the power bus or in Radio Frequency (RF) wireless transmissions. The gaming machine enclosure prevents RF leakage, prohibits injection of unauthorized communications, and serves as a ground. The components may be physically and electrically secured in the enclosure via magnets. Game outcome decisions are exclusively decided by the controller. User inputs are provided to the gaming machine from a remote device, such as user I/O devices that fold out from a comfortable chair or other location convenient to game players.
