This object will point to an instance of a card entry
in the cardTable. The card entry will give details about
the card on which the Flash device is actually located.
For most systems, this is usually the main processor board.
On the AGS+ systems, Flash is located on a separate multibus
card such as the MC.
This object will therefore be used to essentially index
into cardTable to retrieve details about the card such as
cardDescr, cardSlotNumber, etc.
