Chuck Sartor posted:Jim, are you saying that the older 4-6-2's and 4-6-4's are not command upgradeable? I think I have upgraded some of those in the past and they worked OK.
Me too, Chuck. I've upgraded some of that first batch with the modular 103 as well, and even though the process is inelegant and klugey, it does work.
I'm glad the OP was able to get things to function, but I'm still scratching my head over all this.
