The numeric key row above the qwerty keys is 
  inoperable when plugging in a keyboard for use as an input device for 
  VIBS.  The numeric keypad to the 
  right of the keyboard is operable.
   
  This creates a problem when demonstrating ADA 
  capabilities using a big key keyboard.  
  The big key  keyboard does 
  not have a numeric keypad and therefore can not enter numeric commands.  The big key keyboard was selected to 
  meet ADA requirements in Texas that require all controls and operable 
  mechanisms to be operable with one hand including a closed 
  fist.
