It works for me... and four other individuals with whom I work.
In fact, we all are using Adaptec AHA-1542A host adapters,
Archive 2150S tape drives, and Newbury 4380S disks (inspite of
Roy Neese's warnings about bus-arbitration problems with the 4380's)

Anyone out there have a sure-fire way to reproduce the bus-arbitration
problem?  Does the problem only occur with heavily loaded disks or
have we just been lucky so far?  All revisions of Newbury drives?
