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....
