Description:

A trial to make 2 YM2149 reside in same AtariST.The first YM has registers 00-0FIdea is to create a new register set for the second YM on adresses 10-1FFor this we need to memorize, like the YM does for it's selected register, if the top range of registers is selected.
Bonus: if possible, make the design so that more YMs can be stacked :-)
