I have an old Umax flatbed scanner which has not been used since my G4 expired a while back and I'm wondering if I can use it with my mac pro (Lion). It was a decent scanner in its day. If it's still useable, can I use the same scsi card? If I need to spring for a new scanner I'd appreciate recommendations. I don't need super quality but might want to scan in graphics for use with page layout. Also might want to do OCR. Thanks for any insights.
