I hope you guys get the modules back. I'd hate for the lack of it to ruin your enjoyment of Legacy engines. Hard to believe such a trivial portion of the Legacy, and please don't take that wrong, can sway a person from enjoying Legacy and what it has to offer.
I explained a very simple and non-computer way of entering the information, the same as if entering a TMCC engine, for the CAB2. I didn't think it was overly complicated but we all have different tolerance levels for technology.
I would agree to contact Lionel and politely ask to keep the module. I think you'll catch more flies with honey than vinegar.
