(1) The memory space in OOOOH"'3FFFH is the same as
the memory space in 8000H"'BFFFH of the Z·80. The
method of accessing is also the same.
(2) The memory space in 8000H"'FFFFH is the same as
that in the PC·1500. The PV signal of the LH·5803
is used to select the bank for 8000H"'BFFFH. (The
PV signal of the LH·5803 is directly sent by PVOUT
of the SC7852.)
