I may have a set of driver disks for that scanner as I have one that still
works with a good origonal SCSI card.

If yours is the SCSI card that I have it is a wierd one that maps it's self
into DOS UMB memory. Never got mine to work with anything later than Win 95
but then with scanners with 10 times the performance and costing $20.00 now
who cares. <GRIN>
