Ok, got a couple more hours at it this weekend.
Installed the displays, had to replace two display glasses as one was craked and I used one of the good ones to fix a firepower. So had to replace the glass from the one that originally came from FP.
Anyway here they are all lit up...
Does have an intermittant fault where the displays all go to 88888. Must be a connection or solder joint as when I wouch the master display it comes good again. Will look at this next weekend.
Also photo of machine all lit up..
Almost there
