There is no MAT display in the EE bay--only a port for the PMAT. And,
the screen forward of the power levers is not a MAT and is not running
the same applications, but can be used to access limited BITE
information, configuration data, etc.

Some airlines have ordered, as an option, forward displays on either
side of the cockpit near the tillers, which are actually MAT variants
called Side Displays (SDs).  They can use the AIMS cursor control as
they don't have their own trackballs.

The production MAT actually uses a trackball, not a touchpad. I
believe, but am not sure, that the AIMS cursor control is a touchpad.
