finally have the f**king documentation!): 1) Changed all the numeric register offsets to symbolic ones (it should have been this way originally). 2) If 16 bit, disable the shared memory when not using it. Apparantly switching between 8/16bit mode makes the Ultra unhappy unless this is done (i.e. it trashes the bus).
