KIM-1 Piano update

This is an update to my KIM-1 Piano.
In this video I have modified my bread board to include 2 - 8 push down button arrays.
I only had to modify my program by EORing all of the Port A inputs. by placing a 49 (EOR) FF at address 020F and 0210. Which I original had placed two NOPs (EA) in place, so that I would not have to number the entire program.
As you can see in this video, I built a new bread board to accommodate the 2 - 8 push button arrays and I had to use an alligator clip to wire my bread board, as there was no room for the ribbon cable.
