I installed the thing in the RIoCar this afternoon, but the board refuses to work. Voltages seem fine throughout the board, the oscillator is oscillating at 11.2896 MHz like it should, the critical jumpers are set to the proper positions, and the inputs are wired to the RioCar accodring to an earlier post by Hugo. It's being fed +5 volts from the RioCar board off of one of the jumpers. I can't find any shorts or improperly connected components. I only have a six inch lead off of the IIS pads. That shouldn't necessitate a buffer circuit should it? Other than that, the only thing left is to try and concoct some sort of reset circuit, as that pin is currently floating, but I have my doubts that is going to work. I'm not beat yet, but I am feeling very frustrated. On the plus side, the Rio still works.

Anyway, here are some pics so you can at least see what I've been working on.

Any chance that the oscillating components may need to be shielded?
Just a suggestion!
