Good job taming the wiring beast! That looks really good. 8^)
Are you sure? yes | no
It looks very clean, but you need decoupling capacitors at every chip and possibly some electrolytic capacitors throughout the power rails. If you have an oscilloscope you should probe the 5V line all of the way at the end and I'm sure you'll see a significant amount of noise on the line as the computer clocks. This is the sort of thing that causes spurious problems as you add more chips or try to clock faster.
looking really good! the organization and color coding looks fantastic!
Yes, delete it
