This circuit will allow a CPU with a 4 bit address bus to activate actuators by placing/writing suitable addresses on the address bus. He has provided the following text requirement to get you started "...The a/c compressor is turned on by putting a binary equivalent of 0 and enabling the LIOo enable line. An address value "2" gets the 2nd door locked (Door 2)....." He has also sketched out the following system 1 out the IVO control block and generate the required gate level circuitry for it.
