Hi vref,
From A320 QRH - Required equipment for Cat II and CAT III:
Cat II for:
Only one Radio Altimeter but displayed on both sides,
or if no autothrust,
or only one FMA working,
or only one Nav Display Unit.
However we could do Cat IIIB approaches on TriStars with no Autothrust and most certainly with no Map Display.
