I've got two shoeboxes (a 550 and a 550C, with the plastic lift off cover
rather than a hinged door) and none of the 400-type cards installed specify
an REN. And none of the 1A2 BSP handbooks I've got reveal that number,
either. Maybe 400 cards got invented before REN was thought up and WE never
went back to compute or measure that particular characteristic?
