May 29, 2023 - While working with this circuit I noticed that there were times that reading back a bit would be incorrect. It comes down to if I have all the power leads connected and the the power supply to the cores is turned on, then a current spike seems to get into the X and Y wires even if I have not pressed the pulse button. If I first turn on the power supply then connect the power leads, the cores read back their state correctly. I need to remember this for future builds.
