    Abstract: BC9-86-008 MEMORY RE-MAPPING IN A MICROCOMPUTER SYSTEM A microcomputer system has first, low order address, memory means soldered to the planar printed circuit board and can accept further memory means pluggable into socket means on the board. At power on self test, the memory means are tested, and, if an error is detected in the first memory means, this memory means is disabled by directing the lowest order memory addresses to the second memory means and reducing the highest order addresses by the number of locations in the first memory means.
