Well, I identified 3 pins I can move the affected bus to and I even managed to make an updated board layout this morning. I spent last night reinstalling the Microchip development tools on my Windows box and getting things set up to test the proposed changes. I emailed the board shop and got the following good-ish news:
Hi Joe,
Your PC boards are almost completed. We can stop the job however you will need to pay for a new run of boards. The good thing is they have not gone to assembly yet. Please let me know if you want it stopped now.
Thank you
This is good news, because the board manufacture is only about 1/4 of the total cost of the prototype run. If I'm lucky, an $800 mistake just became a $200 mistake.
Now I just need to verify that I can make working firmware with the change. This adds an instruction in my bus decode loop, but I don't think that loop was close to being critical on timing. I made it very simple.
