The 68k processor equivalent of this is Alan Clement's "Microprocessor Systems Design: 68000 Family Hardware". Sadly, the few years the 68k on the Z80 meant that the designs were necessarily more complex, e.g. how 68k bus cycles worked, more integrated parallel/serial interfaces, etc. IIRC there was even a small detour into MMUs, which must have been inconceivable for a home-brew computer then.
