Just a quick question.  If the optional PMMU chip for the Mac II is NOT
installed then how does the address bus get driven?  I'm assuming that
the page address bits from the 68020 are sent to input pins on the PMMU
and the PMMU generates the physical address value.  Is there some plug
for the (ancient) Mac II which passes through the address bits?

The Terminally Curious,
