How retro joysticks worked - RC2014 Joystick Interface Build

Building and testing the RC2014 Joystick Interface. This was a reasonably simple build, but I did have to slightly modify the board to make it work with my joystick. Also I was accidentally sent some wrong components, so now it's just a one joystick interface. The incorrect components sent to me have given me an idea for a future build though!
