Our CPOs definitely faded the same way! I had no idea that it was supposed to be blue until I saw Rich's repro!!
Don't know if you need it, but Kendra told me recently that they have the films for the dedicated side art and that Rich is working on it. She said it will be available soon, and based on my recent experiences, soon is meaning soon.

I don't know if I can switch out my faded marquee, though. (Sorry, Jimbo!) It's in great shape and there's a part of me that has trouble installing a repro when the original isn't significantly damaged. Then again, you can argue that it IS damaged because it's suffering sun damage . . . Crap! I don't know yet, but I'm looking forward to seeing what you do with yours. (Now if the whole marquee lit up on the repro, that would be an easy choice!!)
I hope your joystick issue is an easy fix. If you need, I have an extra sensor I got on eBay that I can give to Jim to give to you the next time he sees you. It's just the modern replacement for the old ones, so it's nothing special, but I replaced the sensors on my I, Robot hall effect joystick and they work well.
