Playstation One (PS1) Controller
Black tubes and grey units are suck/puff switches.
Yellow Velcro holds controller on flat aluminium plate also used with other
controllers.
The connection bar has been wired to all buttons inside the controller. The external switches/wires can then be attached to different scew connections. It is a bit awkward to change wires but it does allow different button configiurations to be used. You just need a screwdriver and a steady hand to change the wires but it is really just like wiring a plug really.
