There's a Fujitsi Scanpartner 300C for sale near me, which is SCSI-scanner with a feeder. I've been looking for such a thing to pair with my Power Mac.

The manual I've found makes no mention of the software, but there's an illustration of it connected to a 'Mac', so I'm guessing it's compatible.

What I'm not sure is how drivers relate to this TWAIN stuff - are scanner drivers generic, or do I need to track down some vendor specific drivers if the seller doesn't have them?
