Hi all. I discovered a bad U113 on my UMK3. There are some graphical glitches. I replaced the socket and verified no bent pins touching on the solder side. No change. I erased the Eprom and attempted a reburn with my PP2, but it fails a few seconds into programming. I'm guessing the rom is just bad. Anyone have a parts PCB with a good U113 or a blank for me?

Thanks,
