Reseated all chips and cleaned pins, still green screen. May have to give up on this one.
Here are some pics of the board. If anyone want to take a look i can post. Cheers |

Actually if you look at the pic, what is the resistor that attaches to the cia a chip, not seen this on any other board. Is it normal?

a green screen dont have to be memory,just memory related.
so that could be 74XXX logic on the data path,or even corrosion on the sockets...if your lucky. |
