You can either purchase the powersupply on ebay and soder it in yourself, have to be good at sodering motherboards, search "blazer cluster power supply"on ebay or try this link found here

Or if you dont want to soder you can just buy the board alread sodered for you by searching for "blazer mb" on ebay, deal with the guy in Winona, MN. Thats who I got my board from for $57.99 found here

I promise that if you get a new motherboard you digital display will work 100% unless the crystal displays are burnt out but I doubt that would ever happen. If it does I have one laying around I could sell.
