How is your arduino / proc powered FLASH project going?

I have a Flash Pin with either a bad CPU board or a bad Master Display Board (maybe connections at the MPU?) I had a technician 'work' on this for a year, charge me for the work and upon getting home to set it up the machine locked up and displays sometimes switch to all 0. Took it back and he basically didn't fix it in the last year, to my dismay.

Well i just got my machine back and the $400 he charged me to not fix it, so now i am looking to fix this myself. In the last year however i have learned about the P Roc as well as the FAST controllers and think my Flash might also be a good candidate. There is a guy in Ohio who has re-themed his Flash to Queen - The Band, all running on either P Roc or Fast Pinball.

Love to see how your project is coming along!
