Re: Cinematronics Monitor Problem

It's definitely a monitor problem and not a CPU board problem. I think
there must be a stuck bit somewhere. If you look at the armor attack
picture, the mis-drawn lines are always consistant. They aren't random. I
guess I just need to look at the scope closer. I just like to get second
opinions because I could be wrong.

the same problem. If you look carefully at the Star Castle MPEG - the ship
in the center is moving left to write and the lines don't stay adjoined very
well. I haven't checked out the vertical section yet, but does anyone want
to offer a suggestion on where to look? It's weird that some lines are
fine, while others go way off.
