I'd contacted you some months ago about the 511000 chips not being compatible to Amiga 3000 - please stop offering those chips! They may be compatible with some extension boards but they're not with an A3k and never will be.
If you don't, I'll buy a set and then you owe me an A3000...
btw: 'without warranty' means exactly that: if the board stops working after some time, it's the buyer's problem. But if it doesn't work right away, it's the seller's problem because he sold it as 'used' which doesn't mean 'dead'. If you have hardware that's dead or untested, sell it as such and not as 'used, no warranty'.
Read eBay's comments, they say the same thing.
