This includes trackballs, spinners and rotary joysticks of all makes. It supports buffered types which include Happ devices, unbuffered (Suzo), high or low polarity. Don't worry if you don't know what these terms mean, there are easy wiring instructions for the various types of controls.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDo I need a power supply?\u003c\/b\u003e\u003cbr\u003e\u003cspan\u003eNo. Power comes from the USB port.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat about mouse buttons?\u003c\/b\u003e\u003cbr\u003e\u003cspan\u003eInputs are provided for mouse buttons. These inputs can be wired up together with I-PAC button inputs so that control panel buttons can perform dual function: mouse buttons and normal key-type inputs. So you could use your trackball as a mouse with two of the control panel buttons working as mouse buttons and also have these buttons work in games via the I-PAC.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat does the labelling on the input connections mean?\u003c\/b\u003e\u003cbr\u003e\u003cspan\u003eThe input connections are labelled Player 1 Trackball, Player 1 Rotary and Player 2 Trackball, Player 2 Rotary. There is no difference in functionality between a Trackball input and a Rotary input. The different terms are used only for convenience. Each of these four inputs has two axes. This means each of these four can handle one trackball or two spinners or two rotary joysticks. There are also power connections. Multiple power connections are provided for ease of wiring, they are actually commoned on the board.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eWhat happens if I have (say) a trackball connected to Player 1 Trackball input and a spinner connected to Player 1 Rotary input.
