I got one of his boards early on I think through planetarypinball supply(?)and tehy would sell out quick! Like he was the official supplier of old boards for WMS product. Sorry I can't remember. The board worked great and saved my machine, unlike the endless headaches I had with rottendog boards that came defective several times. The one I have from the basement is still going strong.
I didn't know about any of the issues or other thread! Got me a little worried about it down the line. Maybe I should send off the OEM one to get de-hacked...
Sorry to hear about all this. I was super excited someone besides rottendog was making the power driver baord for WPC-89.
