Doesn't fully boot - stops at 2H ROM message (the last thing before the game comes up.) ROMS have been replaced - there is a chip (I forget which one) that is involved with the conversion to Rescue that gets insanely hot. Has a couple of jumpers running off to other parts of the board. It's a "partially" working board I suppose. Was working, then I had some power problems and the board started acting up. I cleaned up the power issue but I think the damage to the board has been done.
