Thanks for the clarification.  I you're saying for the 101 and 102 you
start with a core terminal at the factory and they add the options or it's
a field upgrade kind of thing because parts not swapped out easily or
added.  I confirm about the ROMs too, I noticed that the SetUp menus differ
depending on what options are installed.
