Very nice guide, well done sir. You may never have an issue but the risk is there. Many will accept that risk and that is their choice. I myself take the risk as well. I have a product for those who do not want to DIY this and it works for every game no matter the boardset or manufacturer.
My product Game On Interactive Power Supply was made to help these issues. At this time I can only recommend that my product as Randy suggests be used to power all mods but ColorDmd. I do have customers who are running both Pinsound and ColorDmd from the Game On system. I have sent some samples to Randy and am confident he may allow the Game On system as an alternative means to provide power to ColorDmd.
