The Apple Color OneScanner 600/27 is a Canon, I think something like an
IX03035B. It is equivalent to the CanoScan 300. There are newer Apple
scanners, but I don't know whose engines they use - but they're not documented
in the programmers guide to apple scanners.

The OneScanner and Color OneScanner should be straightforward to do drivers
for. The documentation is pretty good.

Someone skilled with MacsBug (like me!) could reverse engineer the protocol
for other Apple scanners from the MacOS. You just set a-trap breaks on
_SCSIDispatch and look at the parameters being sent to the scanners.

But I'm afraid I signed the Canon NDA, and won't be able to do that for you
folks.
