   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   | The only difference between DC-300B & DC-800B is the Cache |
   |                DRAM capability in DC-800B.                 |
   |                                                            |
   |   Remove terminators only when both internal & external    |
   |           devices are connected to this adapter.           |
