I finally have ordered the PCB. I've dragged my feet long enough, but they are paid for. Probably be 2-3 weeks. $60 plus $30 for shipping. I added a bunch of LED indicators for when each module is active. So when I step through the program I can see which chip is enabled. I had quite a bit of board space to use up. Hopefully I don't have too many mistakes (there's gotta be at least one in there). Now I'll have actual hardware to show off (besides an FPGA).
