There's just one problem: The capabilities of the A/UX and MacOS SCSI
Managers are extremely different. Unless the MacOS SCSI Manager is reworked
(which seems about to happen sometime this year, or so it seems), there is
absolutely no way to make it work under A/UX in its full generality.

However, I do have some code which implements a reasonable subset (i.e. the
features 99% of the drivers out there use); but it has one major problem: It
works except "production" environment. That is, I can use it without problems
for issuing commands by SEdit or SCSI Probe, but "real" drivers don't work
yet. I don't yet know why not; the system simply hangs without any obvious
cause. Debugging gets difficult under these circumstances.

I can mail the sources to anyone who is interested in trying to find that
bug. (My own time is extremely limited right now -- trying to write that
MacOS-interface News reading program everyone's waiting for.)
You may need MPW C for the MacOS parts.
