CEI-200 Base Memory Address
Switches 1 through 7 set the base memory address for the CEI-200.
Switches 1 and 2 must be left in the ON position. They are for future
software support. The following table demonstrates mapping of switch
positions to address bits. It uses the default address of D000 (hex) as an
example. The CEI-200 takes up 32Kb of memory space.
