Assignment #10 to be included in Portfolio

You are to improve the 6805 chip by adding more RAM, ROM and I/O ports. The RAM module will be a 64-byte module that is interfaced at addresses $0040 - $007F. The ROM module will be a 256-byte module interfaced at addresses $0200 - $02FF. You will add just two more I/O ports at addresses $0002 and $0003. Show all the decoding logic and connections between the current 6805 (with 11-bit address bus and 8-bit data bus) and the new memory and I/O.
