I stumbled on this Arri SR16 at work which I was gonna try and get running, with no luck. I had noticed that the camera is modded for S16 and has this assist box on the side. Checking the circuit board I noticed that I believe this is an entirely different circuit board as well. I've attached a couple photos of the D-MON and board.
Anyone have any info about this modification? Was going to try my hands and getting this up and running.
