last year I tried that myself, but it didn't always work. Best solution
remains to install your scanner using SCSI if you can.

thanks for your valuable insight. I consider that in the future if it fails
on me again :-)

There are various and sundry ways to share a SCSI bus between 50-pin narrow and
68-pin wide. A cable is one way to do it. Make sure that the scanner's SCSI ID
does not conflict any other devices... Ben Myers

For all the reasons you mention, Christian, I would recommend a separate SCSI
host adapter for the scanner. Something like an Adaptec 2900-series, which are
old, reliable, and fully supported by most any operating system. But the
adapter should not be a "wide" with a W suffix, which have only 68-pin external
connectors.

Use of a separate adapter eliminates any problem with conflicts among SE and LVD
devices... Ben Myers
