                       MISCELLANEOUS TECHNICAL NOTES

    Some versions of this board have two 512KB x 8 DRAM chips mounted in
   place of Bank 0. In such a case the board will work without additional
    memory. In all other cases a pair of 256KB, 1MB, or 4MB SIMM modules
          must be installed in Bank 0 for the board to function.
