All,
I have 2 Pole Position video boards that I am working on and hope you guys can help.
The first gets a "RAM 29" error. I replaced the correct RAM chips, but still get the errors. Any ideas?
The second plays, except for black lines through out the display. I have replaced the ROMs from another board and the custom chips, but I have not been able to find the issue. Picture is attached.
