Micro Assign

i am doing an assingment on microprocessors and do in need of getting 3 or four applications that use microprocessors as a part of the runnig circuit. the microprocessor used in those applications should be either intel8008, intel8086 or motorola MC 6800, but any other different suggetions would be accepted and highly appreciated. by the way, i googled bout that and got some results, however, i still need more results to go on.

cheers
