That's why I was thinking of skipping the clock altogether as I know there are chips that go without it. Yes, there are, like the 6529B in the 264 series. But I think there PHI2 is hidden in the PLA equations for the output that controls /CS for this chip. After all, in this system the PLA generates PHI2... GerritReceived on 2018-03-15 10:05:08
