CEI-220 Base Memory Address
Jumpers A19-A12 set the base memory address for the CEI-220. An
installed jumper selects that address bit as ‘0’. Table 17 demonstrates the
mapping of switch positions to address bits and uses the default address of
D000 (hex) as an example. The CEI-220 takes up 4Kb (i.e., 1000 Hex) of
upper memory block memory space.
