Steve,
MTH Proto Sound be it 1, 2, or whatever does not like the Lionel CW-80. Can you beg or borrow at least a Z1K? If not, do you know someone with a Z4K? To do a reset without a Z4K is at best questionable. Your best bet would be over on the DCS Forum. It's been well over 20 yrs since I even tinkered with PS-1 & 2. Memory is one thing I no longer have, I apologize. Maybe GGG or Gunrunnerjohn will chime in.
