Due to other commitments I have not been able to do as much as I wanted on the clock.
I have added the resistors to each line used (1-7) of the shift registers and made up all the wiring.
For those wondering, I connected both leads of the resistors on the same line and cut the copper trace between the leads.
Looks like a mess, but everything measured and marked.
Here are some photos:
I hope to connect the led's and load the program next weekend.
