I also support a uVAX system here with the same drives but with the Dilog
controller.  We had no problems with the controller and bus terminations,
but we did have problems with our Sigma expansion cabinet.  It seems they
forgot to mention that you have to remove some resistors in the BA23
when adding their cabinet as an expansion box.

I also have good experience with the XMD, we bought it to use in a
high speed data acquistion environment and our intial tests show
we'll be able to perform sustained rates of >1 Mbyte/sec to disk using
optimized writing techniques.

I don't think of this so much as a plug for CDC but as a plug for
using the SMD-E interface. Or at least anything *BUT* ST506/RDxx
toys.
