I need information about interfacing CDC Wrens & Macs.  Specifically, we
received 2 CDC Wrens (SCSI interface, 155MB formatted) without 
much installation documentation, interface hardware, and no software.
While we are trying to resolve the issue with the supplier, we urgently
need these drives on-line.

So far, all efforts to locate either drive on the SCSI bus have failed.  
Either the SCSI bus hangs (no drives found, including the internal HD),
or the systems boots normally, in which case both the Apple HD set-up
program & Ephriam Vishniac's SF&I program fail to find the drive at the
specified SCSI address.

I am soliciting comments and/or opinions from people who have configured
CDC Wrens for Macintosh use.  Any bugs, pitfalls or other gotchas to
watch out for would be appreciated.

Configuration:
	Mac II w/ System 6.0.3
	5 MB memory
	40 MB Quantum internal HD
	CDC Wren 94161-155 (w/ SCSI controller, 155 MB capacity)
	
	Internal drive is SCSI ID 0, system is ID 7.  Drive has been configured
	as ID 1, 2, 3, and 4.  Terminators have been place integral to 
	the drive, as well as on the SCSI cable itself.  Terminator power has
	been specified  as coming from the drive itself (not from the Mac.)
	
Thanks for any & all responses.  These drives are desperatly needed for our
overcrowded file-server.  I appreciate for your time in this matter.
