Is it possible to run a SCSI device, in this case a scanner, from multifinder under AUX 2.0? I have a hand scanner (Logitech's ScanMan) which is hooked up to the SCSI bus and has a program to go out and 1) find the device and 2) read an image. Any ideas if this would still work under the new multifinder/AUX 2.0 setup? --Dwight D.

Why not?
At least the "New" SCSI manager call, as promised for System 7.0, should be
pretty trivial to implement. Just create a special device /dev/scsi and a
special ioctl whose third argument points to the parameter block. Or
something.
The "old" SCSI manager, of course, is another problem.
I don't think it is possible to sensibly map that beast onto the A/UX notion
of how to do SCSI.

It's not impossible but the drivers do not exist. -- -------------------------------------------------------------------------- | Paul E.

Your idea is very likely workable. Gene Dronek (Vulcan Labs) and Rich Morin (Canta Forda Computer Lab) have been developing a /dev/scsi implementation for several platforms, including A/UX. It's been quite a while since we worked with them, but I think that idea's time may come soon. > >The "old" SCSI manager, of course, is another problem. >I don't think it is possible to sensibly map that beast onto the A/UX notion >of how to do SCSI. That's for sure. Might work for some drivers, might be dicey. -- -- Rick Auricchio, Apple Computer Inc, 20525 Mariani Av MS 58A Cupertino CA 95014 sun!apple!rick OR rick@apple.COM Mooney N894AR (408) 974-4227 Never eat prunes when you're famished.
