"WebI can say that my dislike of x86 assembly comes from years of 68000 assembly. The difference in registers is one of the keys, for me. 68000 has simply 8 interchangeable data registers (all 32-bit) for operations to be used with 7 interchangeable address registers (also 32-bit). The whole mess of Z-80/x86 registers is a crazy story. " - Reading x86 assembly
