Re: Asteroids Deluxe

My AD did something similar when I just got it. In the cold garage, I
had a lot of distortion and collapsed video until it warmed up a bit
then it was fine. Below is a link with a youtube video and shows it
returning to normal at about 0:17. Replacing big blue fixed the
problem. Check the video link to see if your machine has the same symptoms.
