Jon, if the TMCC receiver board is not the issue (no programming) then the RCMC board must be where the engine ID is stored or should be stored correct?
Wouldn't it make sense for Lionel to have a backdoor something or other that they can access for programming. If it were to leak, I'm sure the high tech guys here would be able to take advantage of it. If not re-programming, are we talking about throwing away the boards and replacing? I would love to see the production numbers on this set. at 5 minutes per train, it will be a while in the process. I'm glad I can run some other stuff during their absence.
