I'm continuing to push forward with the shake out of the board.
* The SR flip flop isn't working as expected when I strip my system down to just the CPU and Utility card. I've had to bump this up to 0.1uF (from I believe 470pF) to get a reliable poser on reset.
* The Y2 (printer ports) looks to be working as expected. It took a while to figure it out as it's a strange design.
I've been running the board constantly for several days in a basic UART test loop.
* It's ran very solid.
* The warmest the 7805s have gotten is 112F, this is with no forced air flow.
