  Note: The location of W1 is different in the C and CD models. For the C
  model, W1 is located between the floppy drive interface and the drive
  active LED connector.

                       MISCELLANEOUS TECHNICAL NOTES

    The BT-757C and BT-757CD differ in that the ‘C’ model incorporates a
     single-ended interface and software controlled active termination,
    while the ‘CD’ model utilizes a differential interface and standard
                     (i.e. differential) termination.
