I have a Centipede PCB that displays nothing but white dots plus two red dots in the center. I have tested all socketed custom chips, processor and ROM's in a separate PCB and they all test fine. I thought they where bad until I realized that my spare PCB has a 200 series ROM images and this PCB has a 300 series ROM images. I just took them all out at one time and they worked in my Spare PCB one at a time just made the screen yellow was really weird. So Has anyone ever come across this one in their repairs? I know there are a few more 74ls chips that looked a little corroded and I have started shotgunning them already. I was hoping someone may have run across this error before to cut down on the needless soldering.
On the bright side of things I did fix a totally dead Centipede board today was just a missing crystal and two bad character ROM sockets.
Sorry about the glowing ET fingers in the picture I tried my best to block the flash LOL.
