Looking for cause of hot bits on inbound data from SAC interface box

SAC INTERFACE FOR ADDING PERIPHERALS TO THE 1130

Still hunting down the phantom source of the 0x03F0 injected into the inbound data register. It is possible that this could be a hardware issue, since we are talking about six contiguous bits that are hot, but I can test that by using a voltmeter on my driver boards.

I did take the time to walk through the thousands of lines of output from the synthesis report, looking for warnings that I could clean up - not only for the phantom hot bits but just to cut down on errors to make any actual issues easier to spot in the future.

So little time until I get through the crunch time at work.
