Because there really is not much those supported chips have in common, 
yet. The register names are the same - their values and meaning changes.

I rather prefer 5 small, clean, linear chunks of code with a duplication 
of 30% each, than a single big, unreadable and unmaintainable chunk that 
supports all kinds of machines if you set the correct "configuration"
