TOPIC



    What is the value of dual channel SCSI on the Macintosh Quadra 900?

DISCUSSION


    The dual SCSI implementation on the Quadra 900 means several things:

    - Because the SCSI chains are electrically separate, there won't be any
    interruption on the internal chain if something goes wrong on the
    external chain (like a disconnect while the computer is on, poor
    termination schemes, and so on).

    - It gives third parties (and potentially Apple) the opportunity to
    implement disk arrays using the two chips. Micronet is advertising
    their Raven array without using two NuBus slots.

    - You can assure speed of the drive internally using the internal cabling,
    and not limit the speed of a drive by the cable you use (frayed cables,
    bad cables, and so on).
