I know old stuff, but I still have 4 Grinches that work great. What I want is a pcb for DMX to grinch converter. I hate to get rid of my grinches and this would give me more channels just for the price of a converter. I know there were a few out there. So if anyone has a pcb or finished one that they don't need let me know what you want for it. I would like to get two which would give me 128 channels cheaply.
Thanks
