I'm trying to get two Asteroids boards working. Both come up and play but
have graphics problems. All the lines on the first board are jagged instead
of straight. On the second board the small rocks and the dots from the ship
firing are OK but everything else has problems. The link below shows screen
shots. Anyone have any suggestions where to start.
Thanks
Jimmy

Looks like a bad DAC (or the input to it) on the first one.
The second one is probably pretty deep in the VSM. Those
aren't going to be RAM or ROM problems.
If you decide you want to have them repaired, we do
that kind of thing...
