    different signal routing from the version designed for the
    PS/2 Models. Do not interchange these two adapters; always
    use the part number that applies to your equipment.

    Jumper Positions for the 1055 Adapter
    W1 - W2 (Disk/Tape selection): These jumpers should always be set toward
    the middle of the board (the disk position).

    W3 - W4 (+5V & + 12V): These power jumpers are normally jumpered to
    allow + 5V and + 12V to power the external floppy drives or tape drive
    from the internal power supply of the computer.

    It is possible that you may need to have other cards plugged into the
    system that excessively load down the internal power supply. In this
    case, these jumpers should be removed and a SYSGEN external power supply
    can be used to power the external drives.
