The wiring is complete. As you can see, there are many jumpers on the bottom of the board to bring the analog inputs of each multiplex chip to the edge of the board so it will fit nicely in the case.

The single jumpers running perpendicular to the rest supply the microcontroller with analog data from the multiplex chips:

Here is a close up shot of the board. Right angle pin headers have been soldered in and bent to a 30 degree angle to accomodate the length of the plastic connectors for the pushbuttons. Vertical pin headers do not fit since the case is only 3″ high.

The next post will detail the wiring of the buttons and potentiometers.
