Spent some time today on the web site. a) Reworked the 'buying a quattro' piece at http://www.isham-research.com/quattro/caveat.html b) Turned the MAC12D pinout into a table at http://www.isham-research.com/quattro/mac12pin.html Lots of other detail stuff. Comments welcome. -- Phil Payne http://www.isham-research.com +44 7785 302 803 +49 173 6242039
