Thank you so much. I am away this week but I will code up a rom with your code I do have a dual channel scope so I will do what you say.

CLK, seems to be good on z80, and IC31 where it seems to be gated with the iorq to provide crtc E, but as I am not seeing any change in iorq I am not seeing E change.

Thanks again for the time you have spent on this, I will post an update as soon as I have been able to try your code.
