LCD INTF -- LCD Interface Section\n - D[0-23] represent data pins on the 8080 (parallel) bus\n - The MAX7301 is an IO expander acting as the data bus middleman\n between the brain and the ssd1963\n - The lcd control pins will still be controlled directly from the brain to alleviate timing issues and \n because its just going to be easier to debug\n - The MAX7301 is going to be run at something around 20MHz so we should be ok with timing
