They definitely are different and need to be programmed differently. There are no doubts about it. The doubts and problem are that programmers/software, which are supposed to support programming Atmel chips fail miserably here. Do I understand correctly that you also used programmers, which - according to the specs - should be able to program Atmel GALs but they didn't?
