       Although it's certainly true that a decent SCSI controller can accept a wide
    mix of devices insofar as addressing and delivery are concerned, OTOH it's also
    true that slow devices can limit bus speed, effectively bringing all down to
    the "least common denominator". *That*, IMHO, is a strong argument for using a
    distinct (low-speed, cheap) controller for your scanner. Also, with a lower
    maximum speed, the separate bus will more easily tolerate the 6-foot cable
    length.
      Didn't an el-cheapo controller come with the scanner? If not, check
    misc.forsale.whatever , a likely place to find people with extra hardware they
    don't happen to want....
