Re: Tempest problem.

have you checked the 'X' AM6012 DAC @ A10 ? I have seen similar things like this..

If its not DAC related, you need to check the vector timers, one is probably only counting in one direction.

  Ok, seems like there something not quite right with this tempest. I'm pretty sure it's not supposed to look like this.
  Here's the link to the photos.

  First is of the attract screen,
  Second is of the test screen,
  and lastly the cross hatch pattern.

  Any ideas?

  Thanks,
