Is there a clear, concise memory map for the 128's Z80 mode? The one in the 128 Programmer's Reference Guide is just confusing. In particular, where does any Z80 ROM appear, and what's contained in that ROM?
This could help a bit:

Also consult Mapping C128 book. There is no single place with all information inside this book so you will have to search for Z80 keyword.
That definitely helps. Thanks!
