Joe, I'm in So FL. and may have to take you up on the reprogramming. The programmer I ordered will fall short. Even the 6 ROM chips I ordered had the correct description (TMS2564JL) but the picture (KMS2816AP) was wrong. I'm waiting on a reply from the seller to confirm if he was selling my target chip or the KMS #.
I would want to do what you described. Archive the original programming, erase them, then program in the 6 images. Where are you located? Does anyone know how to switch volt-nuts from digest version to individual emailed version?
