Hi guys and gals. If I pull a Tac 20 03 cpu board to have memory chips replaced will I lose any Lon configuration ? They are not touching the Lon chips I currently have one shut down on a 1083 bad recall of non volition memory . It shows b44 on diagnostics screen. Which is Canadian door lock monitoring. I am in America not even in a door lock monitoring code zone. Otis left a floppy disk labeled job back up file. My repair shop hopefully can get the job file from the floppy as I have no computer to take floppy disk
