No matter what other signal you hook up to the NMI line, the CIA will block any attempt to trigger an NMI until it's acknowledged. Unless you do something evil like the ESM circuit, where the CPU is fooled into thinking the line has gone high & so it will see the transition back to low as the sign to fetch the NMI vector.Received on 2018-06-15 01:02:16
