Hi,

I have a 2 player Atari Football that was working great until just recently. Now when I play it, there are a bunch of random symbols on the screen. It doesn't affect gameplay, but is pretty annoying. I attached a screenshot of the problem.

Does anyone had this problem/been able to fix it? Working on PCBs is a little outside of my ability level, so if you know someone reputable that can fix it, please let me know. Thanks!

Bad RAM.

Run the self-tests and see what you get. It should tell you which one is bad.

Urg... that sucks.

It was hard to read the .pdf file on the ASCII archive as it was a VERY poor quality scan.

Next guess: playfield RAM. I wonder if the schematic points that out.
