There is a local Coin-op store with a Naomi 2 on Ebay for very cheap. It's listed as for parts or repair and is said to show the error message: "No signal" .. I'm pretty good with electronics so I was thinking about picking it up. The problem is I don't have an IO board for it and would have to buy a working one -- So the real question is: Does anyone have any experience with Naomi hardware and/or this error?
