Sounds like you have the Blizzard 2060 I bought from overseas, it turned up D.O.A.
I had Anthony look at it but wasn't able to get it going but he pointed out that someone had tried to fit the 060 the wrong way around. I ended up selling it on Trademe as not working.
Lost a fair bit of money on that 2060, it was one of the few times I bought Amiga hardware from overseas.
