You may want to try to find a copy of the presentation Malcolm gave at VCF
East 9.1
(see :
http://www.vintage.org/2014/east/session.php#218)
It's actually on-line at :
http://www.avitech.com.au/disk-imaging/disk-imaging-vcfe-2014.pdf
It had lots of good details and info on a system that he set up and
demonstrated at the session.
