I've had a Qbert project sitting in my garage for 2 1/2 years, and finally breathed a little life into it. If I ever meet the Gottleib engineer who was responsible for the brilliant design of the filter board or power board, I think I am going to punch him in the face.
Good news is that think I'm in the home stretch! The board is working, except the character sprites and the word "Qbert" all have big orange blocks behind them. The ones that are supposed to be red or orange are white instead (see pics). I've removed, cleaned and reseated the ICs--anyone have any other advice as to what to try next?
Thanks!
