I never stated copying. That is your interpretation. I am sorry if I led you to 
the believe that. i would never copy anyones works and call it my own. I do 
give credit where credit is due. Even with a heavily modified code, I would 
credit the original author for inspiring my work. I have no problem with that. 
My ego is not that big. GM code does the best of any code that I have seen 
for a Motorola 8 bit processor in reproducing a near cycle correct core. That 
is my infactuation with that. 

There are a few things that if I may consider changing but that would be 
minor. What I really would like to do with it is to change the command logic 
to microcode and do a super HC12. But patent infringements on the HC12 
may prohibit that.
