You may not need to throw that old scanner away. VueScan knows about a zillion more scanners than what is supported natively in OSX. My Canon N650U came with amazingly poor OS 9 software that didn't even recognize it under OSX. I could use it on my Windoze box, but not my Mac. VueScan is $40, but it worked first time and I could tell before buying if it supported what I needed. One less scanner in the dumpster.
