A friend of mine asked me to look at his DMD display board. It was working much of the time but at some points it would show a garbled display. This is not a board that I expected to see. I'm not sure exactly who made this unmarked clone board. Is this an early Rottendog board? Did others make reproduction DMD boards?
I seem to recall reading somewhere that some games send out a lot more data and refresh the DMD displays faster than others. Perhaps this may work in a different game that doesn't update the display as often. It looks like this is based on a programmable ASIC so maybe there are updates to the code to fix it.
Does anyone recognize this board or know where I can find any technical details on it?
