I have a UMAX 840 scanner (pretty old) that's color/3 pass that used from a local auction (no drivers of course) and I got it with a questionable SCSI port card. It has an external input and no internal support so I assume this is what is called an adapter card and not an interface card correct? Anyways, I've searched the net for a driver to make this thing work so I can use my scanner with it to no avail. Here's all the info from the card.
written on the card:
It's got a blue colored jumper box with white colored switches in the corner, 4 switches.
The main chip on the card says:
<-(scsi cymbol) TolerANT
NCR (C) 1992
If possible include setup instructions for the driver program so I can get this thing runnin with no more headache.
