Interface keyboard and display controller 8279 with 8086 at address 0080H. Write an ALP to set up 8279 in scanned keyboard mode with encoded scan, N-key rollover mode. Use 16 character display in left entry format. Clear the RAM with zeros. Read FIFO for key closure, store its code to register CL. Then write the byte 33 to all the displays. The clock input to 8279 is 3MHZ, operate it at 100kHz. The address of command word is 0082µ. Draw the designed circuit.
