    Why do you think I would be that silly? All of the external SCSI
    devices I use these days are 50-pin high-density single-ended.
    The connectors are more reliable than the 50-pin "Centronics" which
    you might not recognize by its proper name, and the cables are
    easier to work with. I stopped using large SCSI connectors several
    years ago, converting a few old boxes to new connectors, and avoiding
    the use of transitional cables with one end of each type.

    I don't own any HV differential SCSI devices, nor do I intend to.

    Where? In the small TLZ07 box?

    How does the large connector affect the cooling? I would expect
    to read something like this on comp.periphs.scsi, which has a hign
    noise-to-signal ratio, but not here.
