The chip itself was fine but I found a burnt out trace between 5L pin 15 and ground. I'm suspecting one of the 74ls367s 5L or 5M I've been able to reproduce this on the other board when I was working on it. This I take as a good sign because before It was just random garbage and sometimes the game would boot and play. Can't be sure because the game is going through Ram/Rom test then saying Bad Rom 3 then resetting. The culprit was a Bad fixed some of the text in game and sprites.įound a Bad I'm pretty sure this was what caused the double text and sparkles on the screen. I now have some garbage on the screen in the form of letters numbers etc and sometimes the game will boot and play. All you see is starfield and you can see where ship is shooting but nothing else. Up until now I've been able to get nothing on the screen except the occasional starfield and sometimes it even boots and plays. Other corroded chips: 5D,6N,3M,3R I'm sure theres others but cant remember replaced so many. Replaced heavily corroded 368 and 107 at 1E and 1D.This thing was in bad shape board itself was fine but a lot of corroded chips.
