 		 #169338 - I see no con2 connections on your schematic and ...
Responding to: ???'s previous message
while the con2 connections may suffice with the internal pullups in the '51 there is no way the display is going to be visible (except maybe in total darkness) without external pullups on the con1 wires. If you want it really bright you may need a driver (such as an Allegro offering) for CON1.
