=== TODO : UpperROM policy ===
What does I read when a UpperROM is not physically here ?
* if no ROM do read RAM ? [actually what I do (as JavaCPC)]* if no ROM do read a fixed data value x"00" ? [ I'm more about a , x"ZZ" ]?* if no ROM do read a default ROM ? [I don't think about that, no wire-cut effect here]
It shall be nice to do somes tests about that on original CPC.
=== DONE: Another disk selector ===
