Sorry, my terminology was sloppy.  By "card 1" I meant "the card which is
attached to fb1", and this really goes with the "slot", not the "card which is
plugged into the slot".

could see an appropriate flurry of activity in approximately the right color
scheme at each keypress, but the the screen display had no recognizeable shape.
