Hello. I'm looking for a certain date here. When athearn genesis make their models all dcc ready with the 9 or 8 pin socket? Is there a certain year like 2009 or 2010 where all athearn genesis dcc ready models have this type of connection? I know and have seen some athearn genesis that require a board replacement to get the 8 or 9 pin quick plug. I'd like to know if and what year did they start making all their dcc quick plug equipped genesis models available.
