Original motherboard with the plug in sound card. I tried alternative power supplies, cleaning connectors, replacing the big cap, and cutting the trace to the lock out chip. Turns on to a black screen.
I got this along with a top loader NES in exchange for a Retro Duo, so no harm done.
Anyone want it? I can chunk it in a box if you pay for postage. I will not be putting it back together. Plastic casing is thoroughly busted up. No accessories.
