    There are - unfortunately - several SCSI connectors in use:
    25-pin Dsub (looks like a wide serial connector): Avoid them whenever
                possible; they are for the old SCSI-1 standard, have a
                frequency limitation and can possible cause trouble if
                mixed with other (modern) equipment
    50-pin Centronics (the standard parallel printer connector): for
                 SCSI-2, but now phased out.

    The modern ones are
    HD50 50-pin, rather narrow needles, for 8-bit SCSI-types
    HD68 68-pin, same style for wide SCSI

    ... and because some companies want to make some extra profit, there
    is a VHDCI (very high density connection interface), IBM-C60, and
    IBM-C68.

    Unless you have an Ultra-160-SCSI interface, you will most likely
    need an HD50 or HD68 cable. You can look up cables and connectors
    at online shops (www.transtec.de, www.misco.de, ...).
