I'm using a 4380S with the Adaptec 1542A adapter on a RT PC.
It works fine.
There is a little bit of strangeness with the Newbury drives in that
they return a "UNIT ATTENTION" status after a SCSI bus reset and
a dummy MODE SENSE must be issued before it will recognize any commands.
I believe this behavior can be changed permanently by issuing the correct
sequence of MODE SELECT commands.
