Indeed, I have to admit that a lot of the designs I have done in the 
last couple of years have had flash in mind, though as the pinouts are 
pretty similar it's trivial to allow for both.

Ahh, write timing can't be as critical as I thought, will have to 
investigate that at some point, might be usefull for the CoCo/Dragon
