2100H Memory error • No extended SRAM cassette is
inserted.
• The capacity of extended SRAM
cassette set in does not match
"Extended SRAM Cassette
Setting" in the CPU parameter
with the actual capacity of the
cassette inserted.
Stop • Check that an extended SRAM
cassette is inserted. Or, correct the
capacity set in "Extended SRAM
