If there are popular System Busses for Z80 family, 
you know of or you would like to point to, please tell me,
or - even better - contact me if you are ready to maintain 
any "z80bus*" sub page not yet existing, nicely fitting into 
my Z80 series of documents.
This page is dedicated to describe/document System Buses 
well suited for Z80 Family, as well as to describe interfacing
to busses originally designed for other processor families.
