SAC INTERFACE FOR ADDING PERIPHERALS TO THE 1130
I came up with a new design for the logic that sends back word 2 at the end of a transaction, either an echo of what was sent or the requested data, depending on the command type we received. I built it up at lunchtime along with a few other enhancements.
I fired up the systems to test and could see that I am latching up values when I command it to load the shadow SAR, but the values showing on the lights don't seem to match what I expect. Echo works well, but also getting some unique values for certain status words. I am instrumenting the logic to help dig into this further. It is progress, even if slower than I would prefer.
