So, at this time the back side of the main plate is a plate of wire spaghetti. I am not seeing a great way to simplify this too much unless I start extracting circuits from boards and creating my own PCB's (Not my plan, but who knows). Everything works mostly as expected. I have had difficulties with getting sound output at the moment. I believe this to be a missed wire connection or something similar but have not had the time to dig in lately.

For those of you chomping at the bit for more details, I promise to update these pages soon. I have a fairly demanding life and career that keeps my free time to a minimum.
