Ran across it at the swap and snagged it for $35 untested. I figured it was broken and it would be a nice project, and it was! Came with: Model 2 Genesis, one power supply (needs two and it was dead), one controller and the AV cable for the Genesis.
There is a fuse in it, a 2.5A tiny thing, looks just like a resistor on the main board near the audio outputs. Tested everything, and the fuse was the l;ast thing to check and that was the problem. Apparently the power supply got shocked and the fuse blew. Fulfilled its destiny.
I read up on the problem, asked a lot of questions and got this information:
"There is a zero-ohm resistor near the audio connectors on the motherboard."
I go to a couple of friends of mine, a technician and an engineer, and tell them this and they got the oddest looks on their faces. I hadn't even thought of the actual words being used, and they kinda were like "Pallet stretcher" or "box of grid squares" and my new nickname is "zero-ohm" from them.
Anyway, got it repaired and fixed a lot of other stuff in the process. It uses a setup that has two board edge connectors, and tehy were both heavily oxidized. Cleaned them. Took off a little bit of rus tand polished up the RF shielding. Took about half a pound of dust out, wiped off all the grease from the outside, looks really nice!
And works like a charm. As far as Segas go, the Model 1 CD is a rare item. Not terribly hard to get one, but not cheap. Score! And I got to make it a project instead of just buy it, I love that. Pics soon, too dark right now. Got one:
