Hello. I'm looking for an original IC 23 chip for a DX7IIFD. I know that several people may have removed theirs to install the Grey Matter E! upgrade, and may have it sitting in a safe place as was suggested. If anyone does have theirs and is willing to part with it, or knows of a place that I may be able to get one, please let me know. I know there are other places I can look, but I thought this should be my first resource in looking for this item. Thanks. -Dan
