I apologize in advance if this question has been asked before. I would like to upgrade my LOTR DMD to a color DMD; however, this upgrade requires a ROM chip 10.0. I have the original ROM of 4.0 (2003) so it won't work. In order to upgrade to ROM 10.0 is there anything else I also need to upgrade, like a higher chip for the sound board or anything like that, or would the main ROM 10.0 is the only thing I would need to upgrade? Also, where can I get the upgrade chip(s). Marco, Pinball Life???
