Jumper Descriptions

BOARD SIZE
Sets the memory size of the board.
BOARD ID
Determines where a memory board is mapped into the 256MByte space allocated for memory expansion.
HI/LOW MEM
IN maps the memory board into the lowest 256MBytes of CPU type 0 space.
OUT maps the memory board in the address range between 256MBytes and 512MBytes.
1M/4M DRAM
Specifies 1MByte or 4Mbyte DRAM modules.
