As follow up to my original posting, I now have the Newbury 4830S working
under A/UX. I already had modified HD Setup as suggested above to recognize
the Newbury, but the problem was the excessive time the Newbury takes on
bus reset, which makes HD Setup abort on the initialization. The cure was
brute force: I used "dd" to raw copy the partition entries and MacOS
driver to the Newbury drive. HD Setup then saw a drive which did not need
to be initialized, so it allowed partitioning without trying to initialize
the drive, which avoided the abort.
