It seems to the right of it is the X and Y decoders; and to the right of that are various registers to do with X and Y (Y on top, X at bottom -- 9 resp. 10 bits). I guess the top is the pixel sequencing and analog. Hard to tell, we can only see the metal, and that not very good at that :-) Segher Message was sent through the cbm-hackers mailing listReceived on 2011-09-02 18:00:18
