So my Asteroids is nearly fixed. I have replaced pretty much everything on the monitor and it seems to be performing well.
However I still have a slight vector problem at the top of the screen (see pic) that I can't trace down. The problem only affects horizontal lines and happens primarily at the top of the screen. The further down the screen you get the less noticeable it becomes. The bottom of the screen looks fine.
I have done some basic troubleshooting on the board, replaced the electrolytic caps, cleaned and replaced the pins on the edge connector and cleaned the legs of the socketed chips.
It also has a slight hum in the audio but I don't think it's related.
Any ideas are appreciated.
Thanks,
Mitch
