When the RAM module is connected to both slots of Sl:
and S2:, connection is made from the smallest memory
module to larger module and to the main memory. If they
have the same capacitv, connection is made in order of Sl:,
S2: and main memory. A larger capacity memory mustbe
the CE-161 or CE-1600M. Otherwise, the control assumes
as if only the larger module is connected.
