     I'm doing some work with engine management systems and have come across
     a chip that nobody seems to be able to identify. It's fitted in Motorola
     equipment and is a 40 pin dil plastic chip, almost certainly NMOS with
     on board ROM and RAM. I know it has a 4MHz clock and is based on the
     6800, but that's all. The identification numbers on the chip are :-

			 ZC85269CP
			 51R40276505
			 GM58441

     Does anybody have any ideas ?
