I know for a fact that the 29c256 work. Did you make sure the settings are good on the burner?

27c256 and 29c256 are the same thing as far as I know, except the 29 is eletronically erasable (as opposed to the uv erasable 27c) i'd just stick to one of those two

The 28C256 has some pins with different outputs as the other two. So it will not work by just dropping it in.
